	Co2 Quesiton
shawnp2k Hobbyist Posts: 66 Kudos: 14 Votes: 1 Registered: 19-Mar-2006	Ok This is an easy question for you guys with co2 setups, What is the best test kit for measuring co2, is there an actual co2 test kit, And what PPM should a planted tank generally sit around? And thirdly, would it cause any harm to use a regulator / solionde(sp) valve on a yeast canister? I know im sure its just as easy to go buy a canister..but i cant afford on yet and i was given a regulator. Shawn

Absolutely impossible to use a gas regulator on a yeast mix, don't even think about it. Some days you're the pigeon and some days you're the statue.

Wingsdlc Fish Guru What is this? Posts: 2332 Kudos: 799 Registered: 18-Jan-2005	Frank, Worked fine for me! Go head and use the chart but aim for 30ppm as Bensaf said. With a yeast set up, depending on the tank size you might have to run multiple brews. On my 40G I had 3 going. Never tested my CO2 with this but it seemed to make a difference with my plant. 55G Planted tank thread 19G Container Pond [IMG]http://i4.photobucket.com/albums/y118/Wingsdlc/Ric

It simply won't work in a way that will yield good results. Either use Seachem Excel or go with a plant load that doesn't need co2. My Scapes

Doing DIY you will spend all your time messing with bottles and mixtures and all just to end up with an unstable tank. A decent non Co2 method without too much light will be much better, less work and good results - just takes more time. Some days you're the pigeon and some days you're the statue.

shawnp2k Hobbyist Posts: 66 Kudos: 14 Votes: 1 Registered: 19-Mar-2006	I have noticed before that my tank has done very little with the use of yeast DIY setup... However i use at the moment Flourish excel, But i want to make this cheaper in the longrun. My tank is moderatly populated with plants, They are growing quite well with the proper dosage of excell..So Ill just save my money and get a co2 tank. I have the diffuser and Regulator... i was more curious if you could combine the yeast with a regulator setup.. Im impatiant lol.. thanks everyone for your input. Shawn

FRANK Moderator Posts: 5108 Kudos: 5263 Votes: 1690 Registered: 28-Dec-2002	Hi, Because it takes very little pressure to push the CO2 into a regulator, it is probably the only sensible way to attempt DIY CO2 injection. I'd give it a try. Frank -->>> The Confidence of Amateurs, is the Envy of Professionals <<<--
