No I haven't, at least not yet. I have managed to get both diffusers running at 60 BPM which is an increase of 20 BPM on each diffuser. So 120 BPM now. I am going to leave it alone now and reassess in a weeks time.

Lights just going out now after being on for 6 hours and CO2 on for 10 hours. Mosses and plants pearling, drop checker light green verging on yellow. Happy with progress so far.

Doesn't the first stage needle valve act as a flow restrictor? I'm thinking if I turned that down, then the pressure to the splitter would be reduced allowing me to adjust those valves to increase the rate?

@lidz87 I have been reading this with some interest. I've just rescaped my 400 litre Eheim Incpiria Aquarium and re-introduced injected CO2. Clive is right 99.9 % of the time based on my previous experience with planted tanks and as a member if UKAPS. However....I am using a Dupla Drop...

I have emailed CO2 Supermarket with my question. I have a feeling there has to be a much simpler solution to that. Fiddling about with the primary needle valve on the solenoid possibly, reducing the pressure on the Splitter needle valves. Not sure my DIY skills are up to the same as yours. But...

Just exactly how do you dismantle the existing needle valves and replace them with better ones?

Just exactly how do you dismantle the existing needle valves and replace them with better ones?

I'm using a 2 way CO2 Splitter from CO2 Supermarket to run 2 Diffusers in my tank. Question. Do you control the flow/bubble rate via the valve from the solenoid or from the 2 valves on the Splitter? I've got the valve on the solenoid half open, the 2 valves on the Splitter are open just a tiny...

Paul, how did you build your Moss Wall? I'm on the verge of trying it out. Epic fail yesterday trying to use a glue gun to stick JBL Volcanic substrate to a piece of eggshell crate:rolleyes::rolleyes::rolleyes:

Let us know how you get on with this diffuser. I'm betting after a month it will need soaking in bleach after a month so you will need to buy two of them to keep the CO2 going in.

Okay thanks, well at least that's another one of the useless bits of kit I won't be buying. Thanks

I have been tinkering about with some bits and bobs I've got in boxes in the garage to see if I can create my own DIY CO2 Diffuser. Small internal filter and pump fitted with a 3 way attachment, one for CO2 in, a control valve to reduce or increase the water pressure. I could connect this up to...

Can I ask a Moderator to change the title of the thread from Tune to Tunze please. Thanks.

Apologies if this has been asked elsewhere but has any one had any experience with these? https://www.aquapro2000.de/en/tunze-co2-diffuser.html

Did I read that correctly, KH is 24, and PH is 8.2 to 8.4??? Regardless of CO2 that sounds like really hard water, hard enough to keep lake Malawi cichlids or even marine fish. What is driving the PH and the KH so high. If you've got fish in there good luck with them, If I've misread the...

How many litres had your tank got again?

WOW:eek::eek: Oh I do love the lack of the smell of napalm in the morning Thanks Clive, this makes a hell of a lot of sense and will simplify things greatly. So appreciate you taking the time to reply with such detailed, honest and forthright explanations. :crazy::clap: I blame my 23 plus...

Hi Zeus, I notice you have got 2 X diffusers whacking in the CO2 there at a tremendous rate on a 500 litre tank. Have you ever used a CO2 testing kit to measure the amount of CO2 in your water, or are you just relying on the colour of the drop checker? Are they JBL CO2 Diffusers. I've tried...

Hi Clive, Based on our recent conversation in which you replied:- don't recall posting anything specif for 400L but it would simply have been a calculation based on the standard 20 gal dosing, which is: Sunday 50% or more Water Change then dose [3/16 teaspoon KNO3] + [1/16 teaspoon KH2PO4] +...

Hi Clive, I was thinking 120 bubbles per minute was maybe too much, ha ha! I based this on articles I remember reading in one of Takashi Amano's books where 60 bubbles per minute seemed to be the norm, and 120 bubbles per minute was the high end of the scale. Filters are 2 x Eheim's one is a...

Thanks again Clive, I'm so glad you are still around on this forum! Tomorrow I will be adding the buffers to increase the alkalinity KH as you have suggested. There are 400 litres in this tank and it is a closed top. The outlets from the two filters are about an inch below the surface and each...

Sorry, check on page 2 of my journal 'A Shady Glen. Most of the photos on page 1 have disappeared, but the best ones are still on on page 2. http://www.ukaps.org/forum/threads/a-shady-glen-the-recovery-photographs.11352/ Cheers, Steve

Hi, as someone who has tried every type of diffuser on the market, (and I mean all of them) from my experience any inline CO2 Diffuser with a ceramic tube quickly becomes clogged up and stops working. Then you have the messing about shutting off the filter, disconnecting all the pipe work to...

I agree, not sure about the liquid ferts, might wait to see what Cluve has to say. Big fear of providing too much light too soon before the roots have firmly established and in case it just starts off the algae cycle. Cheers, Steve

Hi Foxfish, (still freaked out about that bloody avatar) promise us you will change it after Halloween!! You are dead right about experimenting. I was so tempted last night to drop a few Cory's in there to aid the cycling, but now after reading what you said, I'm definitely going to leave it a...

Hi Clive, thanks for taking the time to give me you input, as ever it is very much appreciated I always seem to remember Crypts melting in the first few days but only if they were bought immersed, I never had them melt if they were bought already submersed. But I agree about the CO2, the Dupla...

Well it's still only early days, only six days in fact since I planted up this project. Not a lot of movement or growth with the plants at the moment, which is to be expected I suppose. I've had the usual melting of some of the leaves on the Crypts which was expected as they were bought...

To start with I have only usd tap water, which in North Wales is not bad. I will be using a mixture of RO and HMA Filtered water with TMC Discus Remineral Pro. No point using RO water at this stage while a few big water changes need doing during the ammonia spike period.

Doing a ater change today after taking the ammonia readings. Readings on day 1 after planting were:- 1. PH = 6.80 2. KH = 0 3. GH = 4 4. NO2 = 4 5. NO3 = 0 5. Ammonia = 0.25 6. TDS = 148 7. Microsiemens = 340 I will set the CO2 on a timer to come on at 11 am and off at 5 pm. Lights on at 12...

God foxfish, please change that orrible avatar it's freakin me out My drop checker is showing lime green and I haven't added any CO2 yet, but it's only the second day.

Thanks gents, I appreciate the advice. To begin with I'm thinking of putting the CO2 on a timer for a few hours each day. Will that be enough?

So after a mega strip down and clean, everything is now back up and running. This time around I've gone with JBL Volcanic as the base substrate and topped it with JBL Plant Soil. Filters starting from scratch with new filter media. Finished planting yesterday. To minimise the effects of the...

Hi All, I have been following Pedo Rosa's journal 'Going Dutch by the Book' and saw a photograph with a link to the name Stephan Mönninghoff so decided to have a look. There is some really interesting and useful stuff about Co2, KH and GH correlation on his blog Extraplant. CO2 (mg/l) in...

Hi Ady34, It’s all down to playing with your bio balls! You can chop them in half or you can mix balls and Siporax together until you get the right balance. That said when I used to use one of these reactors I found that the Siporax got dirty and turned yellow / brown quite quickly, so then...

Hi All, Just a quick update on this. After a lot of messing about and fiddling with the arrangement of the Aquaclear Powerhead and the TMC Aquagro diffuser, no matter what I did, the powerhead started making quite loud and annoying vibrations with the resistance in the water flow caused by the...

Hi All, I just wanted to update the situation I had with getting the right amount of CO2 distribution around my tank, The Full Monty. Having given up on internal glass diffusers, I, like many of us went with the UP Aqua Inline Diffuser and had mixed results from great at first to not so great...

Hi All, Some of you have probably researched this to death already, but I found this video on Youtube which made a lot of sense, we probably knew most of it but I think this guy explains a lot even though English is clearly not his first language, he does it really simple with pictures and...

No problem Manu, re the black algae, the next time you do a big water change and lower the water level use some Flourish Excel in a spray bottle and spray the leaves of the plants with the black algae on them even if they are under water still spray them. Just make sure the solution is not too...

Manu, Sounds like the temperature is fine so no issues there. Yes the more plants you have the more CO2 you are going to need, but remember plants kick out CO2 at night time so it could be quite high in the morning. Steve

What temperature is your tank water at the moment? The thermostat on my Eheim filter is set at 27 degrees at the moment but the reading on the LED display says 30 degrees. With the hot weather I think the ambient temperature is having an effect on the Co2 dissolution and the ability of Co2 to...

Hi all, From my time spent in Germany I got to know the products supplied by Dupla, always dead expensive but there was never any doubt about the quality. Also the first diffuser I bought from Dupla at least 25 years ago, possibly 30, is still available in exactly the same design. That has to...

Hi All, I have been reading this thread from start to finish with avid interest, only took me about four hours, especially going back and forward to photobucket to see the photographs. After reading the first few reviews on this Sera Reactor I was all set to jump on the net, get my credit card...

I have gone from Glass Lily Pipes, Pollen type diffusers, in tank Aqua Do and ADA ceramic diffusers, to UP Aqua in line diffusers. I tried a Bazooka type in tank diffuser I brought back with me from Hong Kong, it worked for about two days and then wouldn't work unless I cranked the pressure...

Hi All, Can I just ask, is it it just me or has anyone else experienced the liquid in the CO2 Drop checkers turning into clear see through liquid? I have two drop checkers, one in each corner of the tank. I have changed the fluid about three or four times in the last few days because it has...

Bertie, Is your UP Inline diffuser installed and set up like the instructions in the diagram below... http://s654.photobucket.com/user/foxfish_photo/media/20bbe095680742bc68682726f8e46ddd.jpg.html

I would work my way backwards starting with the bottle and check each stage. It has got to be something simple. If the bottle is full and you are showing high enough pressure on the gauges the next step is the solenoid, is it connected the right way around, does it get warm when the power is on...

Yeah, they should be fine mate. The check valve is just to stop the water siphoning back down the tube if you have a power failure or your equipment is switched off by a timer. The check valve just stops the water going into either your air pump or your regulator on the CO2 bottle. I have got a...

:D :D Cheers guys this has been very helpful, a lot easier than I thought it was going to be. I should have known someone would have already sussed this out before I presented myself with the question doh! :? I have checked out the thread, cheers easerthegeezer, and checked out the ebay...

Cheers, and sorry, probably should have checked for a thread in the CO2 section before posting. Have you got a link? Also what does the splitter look like, is it made of metal or plastic, I assume it has to be manually switched or turned to divert the CO2? If you know where to buy the splitter...

Hi all, Here is a question which I don't know if anyone has considered before. Problem: 2 x small Nano Tanks set up next to each other, only one running on pressurised CO2 fed from a 2kg gas bottle via an UP Atomiser in the outlet pipe of an Eheim Professional 2 External Filter. I don't want...

HAHAHAHAHA :lol: :lol: :lol: Oh how we bow to her who must be obeyed!! Here is a plan (thinking outside the box) why don't you buy a large very nice decorative vase large enough to sit the FE in and some really nice artificial flowers to go in it. Stick the vase next to or near the tank, the...

So far so good, fingers crossed it stays that way!

Today has been frustrating :evil: It got to the point that even with a full bottle showing 2 bar on the gauge for the regulator the bubbles stopped flowing altogether through the bubble counter. Even when I turned the valve right up on the flow control nothing, zilch, nada. So I decided to...

190 litres. Quick question for you, which way around is the atomiser supposed to be fitted inline. Mine is fitted with the inlet for the co2 coming in from the opposite direction to the water flow i.e at the top. Does it matter which way around it goes? Cheers, Steve

Followed your advice, so far no leaks identified, I noticed the is a strange noise, not loud coming from the atomiser which I presume is the co2 being atomised? :? My regulator gauge is showing 2 bar. I am going to increase the bubble count slowly to see what happens. Trouble is when I ramped...

Hi, This is the bubble counter I am using made by Dupla in Germany. Very similar in looks to the JBL one. http://t0.gstatic.com/images?q=tbn:ANd9 ... Eo6oVSeSV-

My UP Atomiser arrived yesterday, took me 30 minutes to disconnect the pipework, cut the pipe and fit the atomiser, replace everything and switch it all on. I really ramped up the bubble count to activate the atomiser and a lovely wonderful mist of co2 started swirling round the tank. I then...

I went to the guy in Queensferry and he filled all my bottles for £25.00. He also has 3kg bottles which he sells for £30.00 and does a straight swap out with a replacement for £10.00. I am going to measure it up to see if it will go under my cabinet, if it does it should last about 6 months. :D :D

Anyone living near Deeside in Queensferry North Wales tried this place CO2 Services,Bumblebee Garage, Church Street, Deeside, CH54AR. I have got four bottles, 1.5 kg, 2 x 2kg and a DUPLA 500g bottle. The last few times I have had them filled they seem to run out dead quick. 6 weeks for a 2kg...

8) OOooops......I thought it you said it.......Like I said "USED TO HAVE ONE" and only Okay. Now I have got an internal DUPLA water driven reactor which works great, although if I was getting a new one would definitely consider an external one. My next filter is going to be a thermal one so I...

Hi it sounds to me like the reactor is not set up properly. If you turn up your flow rate on the CO2 to 4bps and you have already got large accumulations of CO2 in various places within the reactor you are going to finish up with even more. Eventually the CO2 pressure will build up inside the...

Is an inline reactor outside of the aquarium i.e. in the line between the gas cylinder and the tank or what? Cheers. Steve.

Brilliant, Thanks Ed I will keep you posted on the outcome. Regards,

Thanks again Ed, I know this must sound a little thick, but just exactly how do you tell that the water has 30ppm or that the bubble counter rate is set so that not more than 30ppm is going in. Do you mean set it so that there is not a massive amount going in very quickly and rather going in...

Re: CO2 Confusion? Thanks Ed, I will reset the PH sensor to 5.8 like you have suggested. I seem to remember the last time that I did this it was almost permanently on trying to bring the PH down so that the sensor would switch off. That was because I had discus in the tank and not as many...

Hi guys, Here is my problem, I hope you or someone you know may be able to help. The problem is despite getting what I think is everything right as per the reccomendations and the plants grow healthily (heavily planted with hair grass and riccia at the front, tiger lillies and large leaf plants...
