    When do I exchange my Co2

    Hi all, my Co2 pressure is starting to reduce on the gauge, down to around 700 PSi, when should I look to exchange the bottle approximately? Mark

    Evolution Aqua Complete Liquid Plant Food

    I'm using the self mix ferts via an auto doser, however I'm running half dose every 12 hours as I can't select a specific day on my unit just yet (awaiting app update from Coral Box), however since swapping over the plants are growing well, but I do have some brown algae starting, so wondered if...

    Evolution Aqua Complete Liquid Plant Food

    I have a 400 litre tank to dose, so need a more economical solution here, do they have 5L 10L options.

    bubble counter

    Thanks Tim, I'm using the regulator to gauge the Co2 input, and then fine tune but the bubble are too fast to count so basing most of it from my drop checker and Co2 along with PH morning and night.

    bubble counter

    The water in my bubble counter evaporates every 4-5 days, do I need to keep topping this up or can I run it without water? I'm not using it to count bubbles, as it's about a zillion per second o_O

    Dosing Pump

    Can I get a dechlor filter to fit inside my RO unit, which has the resin filter removed, Will the carbon filter remove Chlorine but not chloramine

    Dosing Pump

    Considering my focus on automation, this is looking very appealing.

    Sorry Ian, I meant dechlorinator:thumbup:

    Dosing Pump

    Hi Ian, that was just an example, current thoughts are 4 maximum, Micro, Macro, water conditioner as I’m on auto water change, and maybe a buffer mix due to the low gh/dk, that said if a motor goes it may be good to have a spare. I know Aqua Medic well as I used to one of their marine set ups...

    Dosing Pump

    I've not really seen a good review on the Jebao dosing pumps, so wondered if anyone had any experience with these, or are they just a rebadged Jebao unit...

    Seiryu Stone and increasing KH

    I'm at the opposite end, my GH is 4 and KH is 2, I'm just trying some buffer I had for a Malawi tank to see if it works and I could do with a small PH increase, however does anyone had a cheap way to get my GH and KH up other than expensive store products. Cheers.

    CO2 system Midlands area

    At the minute I’m using a 50mm diffuser into the aquarium, I’m going to get it running well first and then try moving into the sump as a test.

    Yes twice, i’ll Call you back.......I’m still waiting.

    CO2 system Midlands area

    Thanks Andrew, that’s a good point as I’ve ruled out an in-line option due to the loss of water flow (from what I hear) however do I need to diffuse in to the tank directly or is in to the sump an option?

    CO2 system Midlands area

    I've been waiting for 2 weeks now for my CO2 system to arrive, so far nothing or even an update phone call, so I'm looking for somewhere in the Midlands I can get one tomorrow, it's for a 400Ltr tank. Cheers Mark.

    Water parameters suitable for CO2 injection

    I’m with you here Will, I’m new to the planted aquarium but have fish experience, I’ve just set up a new 400l tank and have tried to automate it as much as possible, one alteration was auto water change, in my wisdom (or maybe not now) was to add an RO unit, after some drilling through walls and...

    How Tall is a 2kg or 5Kg Co2 fire extinguisher

    How Tall is a 2kg or 5Kg Co2 fire extinguisher, I have 24" height to play with and want to get the largest bottle possible, I understand this depends on the regulator, so just trying to get an idea. My friend runs a pub so wondering if this a good route to go down?

    RO Waste

    Thanks HiNtZ that's interesting to understand and I'll keep note of that incase my Ph goes the other way. Tank is now complete, the auto top up is working a treat, 1 x 21ltr change at 12:00 and 1 x 7ltr at 18:00 - 196 litres per week from a 400 litre aquarium (that is a guesstimate). Still...

    RO Waste

    Thanks Ian, I think the RO is pretty similar to the one on your link, I've taken the resin cartridge off and filling from the carbon exit, flow is very good, so I've turned it down at the tap. PH is back to normal.

    RO Waste

    Just a thought here, would there be any benefit to keeping the RO pre filter and carbon filter and bypassing the resin filter to feed the float switch?

    RO Waste

    God guys I feel a bit of a tool, I thought the RO would give me optimum water to start, however reading this and more research, I've probably created more of a problem for myself :banghead: Especially I understand the elements that the plants need more now, so it's looking like a switch in...

    RO Waste

    Ok, here is my report from my local WA. Sorry its quite in-depth, however I'm hoping someone with good knowledge will be able to decide if my RO unit is needed or not? Analysis Typical Value UK/EU Limit Units Hardness Level Soft No standard applies Hardness Clark 2.72 No standard applies...

    RO Waste

    Thanks Ian, I'll get a KH test done as it's a new house but only a few miles away from my previous so should be the same water, I'll also look to increase the water change although not sure if 50% is possible. With a booster pump, how is it controlled? I'm trying to be as automated as possible...

    RO Waste

    I will be using CO2 for sure, as for the RO I do have more fish experience than plants which has covered virtually every fish you can think of over the years, I like not to shock a system and thus the RO made sense doing small changes via an auto top up and adding nutrients back in daily for the...

    I do have 400 litres already stored which we don't use. :meh:

    RO Waste

    I'm going to run a small pond pump from a timer, just need to work out how long to set the timer for. ref the boost pump I'll see how it goes first.

    RO Waste

    I have 475 litres to deal with, I'm going to aim for a 13% water change per week, 63 litres at 9 litres per day. I'm thinking of sending the waste to the garden plants.

    RO Waste

    Many thanks Ian, I've just ordered an automatic shut off valve from RO Man, this will do the job perfectly. I'll test the water once I'm up and running.:thumbup:

    RO Waste

    It appears not to be very efficient 1 litre of waste takes just over 3 minutes and 1 litre of clean around 8 minutes :nailbiting: So the waster will produce 38,000 gallons a years based on these figures, which is just not ethical.

    RO Waste

    Ok I'm scratching my head here, I've fitted a new RO unit yesterday I knew there was a waste pipe however I wasn't really prepared for the amount of waste, the system has a regulator on the waste pipe which is shut off but allows a pin hole to remain open at all times, the only logic to me here...

    To RO or not to RO

    Just installed my first RO today, I will have a small pond pump in the sump which is plugged in to a timer, it’ll run for 1-2 minuets per day to drain a few gallons, RO will be linked to a ball valve for auto top up. Go live will be in a few days.

    Auto Top up - Fridge filter system.

    Thanks all, I can't syphon out so I'll have to pump it to waste, just drilled a sneaky 1" hole from the back of my aquarium through the wall and discreetly in to the utility room under the sink, connected to a spare drain fitting which has a flap washer to stop backfill, I've lifted the pipe as...

    So who has the best aquascape right now on UKAPS, and lives in the UK...?

    Hi mate, I get t them from Shirley aquatics, however there was Asian text on the packet, I’ve sowed 2 types of seed, but also planted some well known plants as back up. Will wait to see what happens, and I’ll update on here.

    Auto Top up - Fridge filter system.

    Hi All, from what I'm reading I'm going to have to do more water changes than I had originally thought, as time is sometimes hard to come by I've decided to create a auto water change system in my sump, I'm planning to add a small pump to the sump, connect it to the waste under the sink, loop...

    So who has the best aquascape right now on UKAPS, and lives in the UK...?

    Some lovely aquascapes on here, so here is my progress after 5 days, a mix of seeded and planted from a semi dry start. This is my first attempt at a real scape although I have worked in aquatics many yeas ago, however the technology wasn't to the level it is today. I'm more of a fish keeper and...

    Reactors - separate up or inline ?

    Can you oversize the reactor, step up from say a 12mm to a 16mm pipe, then down to 12mm again, thus the bottleneck will be enlarged?

    Seeds for Carpeting plants - Myth or Real?

    I have purchased some seeds like this today from Shirley Aquatics, they had a couple of display tanks planted with this method and also had some growing in small tubs as an experiment, I hope I haven't wasted my money as all the seeds are now on the substrate, I've just kept the base at water...

    Have I dropped a B

    I was thinking of a clay based course like manado topped with tropica soil or some shrimp soil, running from 3”-6”? Co2 set up (suggestions welcome) the JBL range seems good value. I’m running a sump filter through bio balls, then through 3 layers of foam, in to 3 litres of k1 micro, then...

    Have I dropped a B

    Thanks Ceg / Ian, the LED light comes with an app so I have full control and it also has sunrise and sunset built in which I think is a nice touch but understand it doesn't make a difference to the plants. I was going to keep the 2 T5's in place in case I need a bit more, or I'll add a second...

    Have I dropped a B

    Hi all, I'm transitioning to a 60x22x28" aquarium, the tank used to have 4 x T5 lights, however as one ballast was playing up I decided to switch the front to LED, I purchased an 148cm Interpet Tri Spec light which was recommended by my local aquatic specialist. I do intend to add CO2 and a...
