co2

I have a problem with my bubble counter, when it's full of water the bubble count about 1 bubble per second but after the water evaporates, the bubbles increase, at 75% of water, the bubble counter is about 3 bbs, at 25% of water, is about 4 bbs. In other words, the pressure increases when is...

Hi everyone I have a 70 L planted tank and would like to get CO2 on it as liquid CO2 doesn't seem to work too well for me and I really want to boost my plant growth (ive never been able to achieve pearling yet either :() I've been considering a few options as I have a fairly low budget...

Hello, I would like to have the chemical explanation of why water taken out of a tank, in say a cup, will have its PH rise and be > to the PH of the water in the tank. This is assuming the following: The tank has some aquasoil that buffers PH. Co2 is not being injected at the moment water is...

Hi, For the last 2 years or so I have been fighting a battle with BBA! I've tried bleach and H202 to no avail. Yesterday I tried again, soaked my rocks in a bleach-water mix, pulled my plants to bits, getting rid of all those ugly black leaves, cleaned the filter, etc. Gave up on Co2, but...

My previous scape in this tank ended here: The Island - ADA 75P - It's been a while.... Easy title as i'm hoping that after just 3 years in hobby i've at least progressed a tiny bit and able to put into practice what i've learned so far (with a lot still to learn). Main idea of this scape will...

So I found a kit for Co2 but I just need the bottle/canister. Can I use wielding canisters and such? Im hoping to get a good month out of it at least but I don't know what size I should go for? any help is appreciated I admit Co2 might be overkill but I want to give plants best chance they can...

Hi All, I'd really appreciate some advise from the CO2 experts! I've just installed my first CO2 reg (CO2 Art Pro SE) using the Sodastream system (space saving for now!). Running at 1 bubble/2 seconds in a 55l heavily planted cube as a starting point. All working, no apparent leaks, but I...

hello, so i use Ro water and i would like to remineralise it with seachem equilibrium but I'm aware that this has no affect on Kh. so my question is can i use reminerailse my ro water with only sachem equilibrium even though the Kh will be 0? i use Ada aquasoil and my co2 is at 30ppm, i also...

Reaching out to those that use co2 fire extinguisher’s on there planted aquariums where’s the best place to buy a 2kg bottle from either online if so what websites also if anyone is local to Norwich where to buy in the city :) much appreciated :p

Just curious, does anyone know how much a CO2 bubble weighs?

Hi all, I recently had a cheap Wilko plug timer conk out on me, resulting in my Co2 running 24hrs a day for what must have been the best part of a week. I've replaced the faulty timer, but unsurprisingly I'm now facing Co2-related algae issues in the form of a particularly nasty staghorn...

I am hoping someone can assist with the following problem. First of all, I am very new to this, so I could be doing something very simple wrong. I recently bought a CO2 art regulator, and I am having a very difficult time using the working pressure knob – notably reducing the pressure to...

Hi Folks, It would appear that JBL have decided on a new optimum CO2 level in users' tanks. Instead of the 30 mg/l figure, which has been 'the norm' for a good many years, JBL seem to be rolling out their latest drop checker (DC) test sets with a new optimum of 20 mg/l. See below...

Sorry if this has already been discussed - I did search for "passive CO2" but couldn't find anything, so here goes: I recently stumbled across a video showing an aquatics shop in San Francisco, "Ocean Aquariums" (misnamed as all freshwater!) where the owner does things a little differently...

What is your preferred method of diffusing CO2 in your aquarium?

Hi, I'm thinking about adding CO2 to my Juwel Vision tank but it doesn't have the original cabinet. The one that came with it is quite a bit shorter and the cupboard's internal height is only 46cm. Is it possible to fit a CO2 system or is the space too small? Looking at the dimensions of a fire...

Hi Folks, I don't understand why a 1pH drop is advised when setting up a profile for injected CO2. For example, if the water KH is 4dH and the starting pH is 7.3, the CO2 concentration will be approximately 6 ppm. But, after a 1pH drop to 6.3, the CO2 concentration will be a staggering 60 ppm...

Hi Folks, Would anyone care to quantify fluctuating CO2 levels? This term crops up a lot but exactly what does it mean? The word 'fluctuating' refers to something that varies with time. So, when we refer to fluctuating CO2, are we referring to CO2 levels that vary throughout the photoperiod...

Hello everyone! I started my first iwagumi style tank (nano) just this summer. Since I have a nano tank I bought the DOOA CO2 System Kit cause I Thought I looked cool. https://www.aquasabi.com/DOOA-CO2-System-Kit Little did I know then of the problems I would run into. One of them but also...

Hi Currently have an external qanvee atomiser, this works well and have no issues however I am rather lazy when it comes to cleaning it and is abit of a pain to clean if I’m honest. This laziness probably causes my co2 to drop off at times which can be an issue. Thinking of switching to an...

I have recently bought a JUWEL LIDO 200 which I have Aquascaped and planted moderately-heavily. I set this all up without considering the need for co2 or perhaps an upgraded filtration system as the one that comes with the tank isn’t good enough and doesn’t look very nice. I have been...

Been battling it for a month. Using toothbrush to scrape it off plants. The worst part was the sponge filter it loves porus materials. I didn't think it would work or in fact would make it worse.. but thought I would try it as a last resort option. I completely shut off the co2 and after a...

Recently finished building a Paludarium that a managed to seed and obtain a good covering of Glossostigma on the floor. All looked good until I filled with water, and within two days it all started to die. After doing some research I came to the conclusion that there wasn't enough CO2 in the...

Hello, I have just set up my co2 system. The diffuser is now full of co2 and there's no water left in it. My issue is that there are not many bubbles coming out of the diffuser at all. I have it at 1 bubble per second and the diffuser has a tiny amount of bubbles? Is the correct or is...

Hi im moving my shrimp to a 125l from a 27l and have been using an ro filter which was 25gpd I've now upgraded to 200gpd and wanted to check as I'm still new to using RO water it's reduces to 4 tds from 450 which I presume is fine as it's about 99% and waste is at 1:1.25 when I measured. Just...

So you've planted a bunch of in-virto plants and have flooded the tank. You got the co2 running, lights on and filter flowing. Now what? Currently with my tank, some of the plants are melting back (which is to be expected), the light is on the lowest setting running for 6 hours and co2 is on...

Hello, I've run into a really annoying issue with my regulator. The stupid c02 tubing keeps popping off the push fitting. I had my psi set to 40 and I'm using an intank bazooka diffuser. Is there a way to remove the push fit and replace it with a lock screw fitting instead?

Hey everybody So I’ve a Juwel Lido 200 that I think is ready for an makeover. I’m looking to go heavily planted but have no co2 etc as of yet (just the lights/heater/filter). Happy to go co2 to ensure a better balanced tank. We can talk everything from substrate to hardscape to plants. All...

Hi I have a 240l tank that I have now converted to a high tech planted tank. Ive decided to use RO water and remineralise as my tap water is terrible (about 60-80ppm nitrate and very hard water) and have been deciding on what parameters to aim for and so far ive settled on a pH of 7, GH of 6...

I've been reading and watching videos to recap on this hobby again after a long break I saw a video where someone said that I have to do water changes everyday for the first week, then every other day for the next 3 week's. Then after that I can do weekly water changes. Is this necessary...

I have had a 64 litre tank for a few years, and on the whole few problems. I have now splashed out on a Juwel Vision 180. My tank is planted, and I seem to be having issues with plants dying. It has been pointed out me that Co2 is my issue. Needless to say I feel quite thick after been a...

Hi, Considering setting up a 2Kg fire extinguisher co2 setup under my RIO240. Has anyone had any issues fitting this in the supplied cabinet? Mainly concerned about height of the cylinder and regulator (probably co2art SE) Thinking a 2Kg firechief CO2 extinguisher Thanks

I’m been attempting to grow Utricularia graminifolia as a carpet plant in an 15 gallon iwagumi set up. This led me to do an online search to see what conditions have worked for others. In addition to the usual specialty web sites I looked at various blogs as well. So what follows is the progress...

I'd like to get opinions on this method of adapting plants to life underwater after a dry start. What are your experiences with plants adapting after dry start method? Specifically with Dwarf Hairgrass (acicularis eleocharis sp. mini), anubias, and Ludwigia Mini Super Red. Or otherwise, has...

I would like to set up a small iwagumi styled tank, 20 gallon long or maybe a 30 gallon. 20 gallons is 75 litres in metric. I dont know what equipment i need though No tutorial or guide i've foud really goes over the lights, co2, or any of that sort of detail. I would like to know some...

Hi I'm looking for a CO2 set up for my 140L tank. I'm currently looking at regulators and they seem to be the most pricey bit. Anyone recommend any that are sub £100? I don't have a Huge budget but want to give my plants the CO2 they deserve.

Hello i'm new to this forum but have been ghosting for years. I have been battling algae for a while and i'm starting to give up, its not bad but very fustrating trying to balance everything. mainly on the annubias and some buce, but also some bba on the tips of my tall cryps and they started...

Hi all! So I’m looking to purchase my first co2 system for a 15g tank. I’ve found one on co2supermarket which seems to be highly reccomended by the lovely people here on the forum. I just have a few questions before I take the plunge. Firstly concerning the choices for ‘Solenoid Type’. What’s...

Hi Folks, Does anyone use (or tried) the JBL Direct CO2 test kit? I am referring to the following: https://www.jbl.de/en/products/detail/6449 I decided to try this kit as it gives an instant (well, 5 minutes) measurement of dissolved CO2. I thought it was worth a try as I get frustrated...

Hi Folks, My new glass conventional drop checker is giving misleading readings. And I have good reason to believe that it's being caused by a white film that builds up near to the DC entrance. In other words where the CO2 gas diffuses from the water surface to the airspace inside the DC. See...

Hi Peeps. On my 2000L sumped setup, Ive noticed that my drop checker is almost lime green BEFORE co2 on. Noticing this every day lately. Anyone else had this happen? Drop checker liquid changed, turned the lights on (with co2 off), and got some pearling. So I dont think its the measurement...

Hello fellow UKAPians. I need some advice/logic. So I have a FE connected to a single stage regulator. When I got home the FE handle had popped open the duct tape I used to seccur it. The inline diffuser still hadn't filled up with water (which meant that it had happened within the last hour...

Hello - I am new to this forum. I've had a small aquarium for awhile, but am upgrading it to a larger one for more fish/plants. I will be having a CO2 line and have a few questions on valves. Are most people using solenoid valves on timers?

Hi I set up a regulator with seloniod to a fire extinguisher yesterday afternoon. The tank or cylinder (high) pressure was around 850. The seloniod turned off at around 6pm. This morning I checked and the pressure has dropped to 800. I checked for leaks yesterday, once with seloniod off and...

I have an Aquario Neo diffuser and was wondering if the bubbles coming from the pipe at the bottom of the diffuser would work fine as a bubble counter (maybe it would have uneven flow?) I don't see a need for unnecessary clutter so I'd love to not have to buy an inline one. Cheers

Hi guys, I'm sure you all know how to make co2, but i made this video to help newcomers to planted tanks. With such an easy way to make co2 and the massive impact it has on your plants, it should be a must for most planted tanks (that have any decent depth to them). I know i found this forum...

Hi guys, Well, I'm still a good deal away from setting up anything yet, but I'm using my time wisely to do lots of research. Whilst I was looking at possible CO2 sources I came across something called "food grade" CO2. Does anyone know exactly how this differs from the CO2 in fire...

Hi, I've recently set up a 25l tank. I hooked it up with a 95g CO2 canister that is fed into a JBL inline diffuser. For the first two days I was releasing about 15 bubbles a minute. Then on the third day I got a drop indicator the only way I could get it from blue to green was to do about 60...

I've ran air-stones at lights out, I've ran them 24/7 with co2 cranked up to compensate. The battle for good oxygen levels without de-gassing co2 always seems to take place at the water surface which recently led me to an idea/experiment. What if I create "another" surface which I can aerate...

Firstly I apologise if I've posted in the wrong area, I can't seem to find a section on Aquariums (i.e. the actual glass tank). We're thinking of purchasing a second tank and I've been looking at various sizes of nano tanks (up to 55l). Can anyone tell me if the smaller nano tanks (ie the...

Just to experiment I've taken off the diffuser on my nano and have fed the co2 line direct into the filter intake. There is clearly co2 collecting in the canister, when i shake it it burps out. But it's not making any additional noise. Are there any long term problems with this approach?

Bought a new dual stage kit from CO2Art last week which arrived quickly and nicely packaged. Impressed with the quality of all the kit for the price and is always nice to see good value doesn't need to mean the quality suffers. Spoken to Karol regarding a few things with setup and their...

Anyone had any experience of the older Co2Supermarket dual stage regulators? They don't sell these anymore and have replaced them with a different version so struggling to find any info on it. Been offered one for a good price after I've been looking at the Co2 Art ones (brand new) and just...

Ive looked online but can’t seem to find out whether I’ve set up my pressurised co2 system properly (it came with no instructions) I’ve made a quick video, if anyone knows what I may have done wrong, I’d appreciate your advice, thanks!

Hi everyone! I'm planning on purchasing a Juwel Lido 200 next week. It will be the first time I've used CO2 and tried to aquascape. Any tips for a beginner? My dad and I have always kept aquariums but this CO2 introduction has made me nervous! If anyone knows a decent place to purchase gas...

I have just converted from using an in tank diffuser to an external reactor to mix my co2 and eliminate the fizzy look. Using the diffuser, my pressurised sodastream system ran at about 2 bubbles per second and turned the drop checker to an ideal lime green. Now I have the co2 running at 3...

Hi I'm pretty new to the aquascape scene and just wondering if anyone has any advice on how to know whether or not i'm overdosing the tank using Liquid Carbon. The CO2 Gas type looked a bit "Pro" for my needs, but after much reading i may end up going down that route anyway. For now, i have...

Hi Tried 6% h202 on my diffuser but very little is clean, left over night and tried liquid carbon too and still algae is present. Bleach the only option left? I thought of trying Cola or something has anybody tried that? Gonna move it out of the light next time I think... I have an inline...

Is it the level of CO2 solubility can affect the GH level?

I started using pressurized CO2. Currently drop checker is green, my KH is 7, Ph 7, so I should have 21ppm of CO2 at all times. I have 250l tank with 3x39w T5 light bulbs. However, not a single plant pearls. I've noticed a stream of bubbles from Anubias nana leaf, but that's it. I expected my...

Hi. I have I question about easycarbo.:) I brought some at the weekend and started dosing it every morning before I go to work. The timer on my lights are set for 1330pm and I'm planning on dosing at 0630am will It still work or will I be just wasting it? how long does it last for?

Hey, I used to frequent here alot a few years ago before getting pulled into marine for a few years. Due to huge building work at home I closed down my marine tank and have been thankless for the last 6 or so months, then I got the itch to go planted again... So here we are! A few of my...

Hi All, I am new to this forum but I have been directed here for some useful advice. A little bit of research: I would like peoples opinions on CO2 reactors and Diffusers (ceramic) and which would be better for a large 6ft aquarium. I have read multiple threads on different forums, some...

I have recently purchased a Fluval 88g System. I have read up on it and apparently the disposable cartridges will drain my wallet even on a 60L. I do a little shooting with Air Rifles and use a pressurised (diving bottle) to fill them up with. I believe it is a 3 litre bottle. Would I be...

I think something that isn't emphasised enough to beginners is the value of a surface skimmer. When you’re starting out there is a good chance that you are going to battle a bit (or more likely a lot) getting the light Co2 balance and flow just right, this leads to imperfect plant health, which...

Hi all, Recently bought myself a Fluval mini Pressurized Co2 System (88g) and was planning on using it in a 30l cube to aid my 'cuba' carpet when I set the tank up. This is probably a really dumb question but if I don't ask I will never know. So do I have to use the tiny refill cartridges, i'm...

I recently installed a co2 pressurised injection system on my Roma 240L aquarium, I started by injecting at a rate of 2bps, but found I had to increase this to 4bps to maintain a nice green DC throughout the photo period.

I have recently set up my 54 litre (2 feet by 1 by 1) aquarium with pressurised CO2. Initially for a few days my plant load inside the tank wasn't too high but I would nevertheless leave the CO2 on with lights for the Java fern and an anubias and some freshly planted Cuba. There would be...

Hi folks. When adding new stock, is it a good idea to turn off CO2 for a few days? I added 6 Lampeye Tetras to Hobgoblin's Cave last week. 4 are already dead, 1 doesn't look too good. All existing stock is OK. Any thoughts?

I'm not a chemist or botanist so trying to understand the ideas behind use of CO2 in tank and how to find the sweet spot where things work well. I'm confused by the word diffusion. I have a 'diffuser' which creates a mist of fine bubbles and I'm trying to find a way to create good flow in the...

Hi guys, I currently have a 90 gallon tank. Water is 77 degrees Fahrenheit. My CO2 runs from 9AM-7PM at about 4-5BPS, my LED runs 10AM-3PM(15min fade out), and my 2x54T5HO run 2:40PM-8PM. I dose all flourish products: excel (every other day), potassium and iron (once a week), and flourish...

So I'm just wondering about this new CO2 set up I'm using. Can anyone clarify this doubt I have. If I have a spray bar returning water into the tank from an external filter is it true that it shouldn't create any water disturbance on the surface of the water? In other words, should I be angling...
