cainechow Posted March 2, 2012 Report Share Posted March 2, 2012 What is everyone using for CO2 diffusing? DIY reactor vs, ceramic/glass vs. ? I was planning to build a DIY PVC reactor but came across http://www.dealextreme.com/p/aquarium-fish-tank-co2-atomizer-system-8-12mm-hose-107659 today. Seems kinda small to be effective enough to fully diffuse CO2 before it gets spewed out the other side. Thoughts? Quote Link to comment Share on other sites More sharing options...
jvision Posted March 2, 2012 Report Share Posted March 2, 2012 I just put the CO2 into the INTAKE (not the Venturi) of a powerhead. I creates a fine mist and disperses it throughout the tank. Quote Link to comment Share on other sites More sharing options...
ubr0ke Posted March 2, 2012 Report Share Posted March 2, 2012 What is everyone using for CO2 diffusing? DIY reactor vs, ceramic/glass vs. ? I was planning to build a DIY PVC reactor but came across http://www.dealextre...2mm-hose-107659 today. Seems kinda small to be effective enough to fully diffuse CO2 before it gets spewed out the other side. Thoughts? They work, but I heard were a pain to clean. They also need a higher delivery pressure so if your regulator has a delivery pressure of 40+ psi then your ok but if not don't buy one. Ive used every kind of diffusing method other then the atomizer and every way has its pros and cons. A pvc reactor works well but you need to run a venturi so gas doesn't build up or it can get noisy. A glass diffuser works well in smaller tanks but you need to keep them clean. Soaking in tilex every now and then will keep it clean. A powerhead works well but it wastes co2 but i suggest doing a needle wheel mod if using a powerhead.

Vallisneria Posted March 2, 2012 Report Share Posted March 2, 2012 I use a little Elite mini filter and run the co2 into the intake. Quote Link to comment Share on other sites More sharing options...
jeremoose Posted March 2, 2012 Report Share Posted March 2, 2012 I'm currently using a glass/ceramic diffuser and it seems to work great, although it hasn't been in use that long yet and I don't know what cleaning it will be like. Quote Link to comment Share on other sites More sharing options...
ckmullin Posted March 6, 2012 Report Share Posted March 6, 2012 I also use the intake. Put it in the fuval 305, works like a charm. How many feet of hose...intake/return...the action of the filter materials. Not a poop comes out that you can see. Quote Link to comment Share on other sites More sharing options...
bero Posted March 6, 2012 Report Share Posted March 6, 2012 You guys think that the intake to my aquaclear would work the same? Quote Link to comment Share on other sites More sharing options...
ckmullin Posted March 6, 2012 Report Share Posted March 6, 2012 what size is it? Quote Link to comment Share on other sites More sharing options...
cainechow Posted March 6, 2012 Author Report Share Posted March 6, 2012 For you guys using the filter intake, are there no problems with the bubbles messing with the impeller action? Or is the CO2 completely disolved by the time it gets to the pump? Quote Link to comment Share on other sites More sharing options...
ckmullin Posted March 6, 2012 Report Share Posted March 6, 2012 no problems here Quote Link to comment Share on other sites More sharing options...
Vallisneria Posted March 6, 2012 Report Share Posted March 6, 2012 I'm just using the little elite mini(also used an AC powerhead) but I've not had any issues with the co2 bubbles causing problems with the impeller. It does make a little bit of noise when the co2 goes through the filter but never had a problem with the impeller skipping or stopping. If you're worried about the bubbles being too big for the filter you can always hook an airstone up and have that flow into the filter uptake.That way a mist of bubbles is being sucked up instead of big bubbles. I've also tried it that way and it worked great except my airstone(a wood one) made this weird high pitched noise from the bubbles coming through it that I switched to the elite mini way instead.

bero Posted March 6, 2012 Report Share Posted March 6, 2012 (edited) i have a aquaclear 30. im also using a small elite filter but it seems just to blows the bubble into a bunch of smaller ones. doesnt seem to diffuse super great?

ckmullin Posted March 6, 2012 Report Share Posted March 6, 2012 one of the things with a canister filter is the total distance the bubble must travel before it gets back into the tank. many feet vs a smaller HOB filter. give what Villisneria a try..use an air stone first.

Edward Posted March 7, 2012 Report Share Posted March 7, 2012 I use a Rio 800 and a gravel cleaner tube. Run the hose into the gravel cleaner, attached a wood airstone from Lee, and put a sponge in the bottom, seems to be working very well Quote Link to comment Share on other sites More sharing options...
