DIY CO2
Hi there,
I've been kind of lurking here for a couple of weeks, but I now have a question. With some help from the greatest LFS that I've ever known, I put together a DIY CO2 unit today. It's the most basic one, a 2 litre pop bottle, a checkvalve, some airline tubing, a rubber stopper, and an airstone. I've had the solution ready for about 1.5 hours, and hooked up to the tank for about 1.25 hours. I'm already seeing fizzing through the wooden airstone, so it seems to be working REALLY well! My only remaining question is - what should I be looking for in changes for water chemistry? My current water is: pH 7.8 No2 0.1 No3 0.0 kH 100 GH 200 Thanks! -- Martin Moran ommoran at telusplanet dot net Beaumont, Alberta remove "no.spam" on replies http://www.telusplanet.net/public/ommoran/publickey.txt "When you're caffeinated, all is right with the world" PGP Public Key Fingerprint: CEF6 48D8 73FC 2A36 3287 FC20 CAEC 75D1 9C58 B861 |

YOur pH should start to go down. YOu need to know the water hardness and
measure the pH and make sure the co2 level (computed from the two values) does not get too high. Use Chuck Gadd's wonderful calculator: http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm Lots more info on co2 injection, mostly about pressurized co2 systems but a few items on DIY co2. http://members.cox.net/tulsaalstons/...Pressure%20CO2 -- Bob Alston bobalston9 AT aol DOT com "Martin Moran" wrote in message ...

FWIW, the diy co2 WILL clogg up that wooden airstone, its much better to just pump it directly into your filter intake. Heads up! -- **So long, and thanks for all the fish!** "Martin Moran" wrote in message ... On Sun, 31 Oct 2004 11:29:30 -0600, "Bob Alston" wrote: YOur pH should start to go down.

How will the CO2 clog up the wooden airstone?

DIY CO2 is dodgy to say the least, ask me, I use it exclusively :-) There always seems to be a fine film that runs down the tube and it inevitably will clogg up airstones. Diy Co2 juice on the ceiling is just no fun I tell you. Better to let the bubbles escape the tube uninhibited into your filter intake. -- **So long, and thanks for all the fish!** |

The moisture from the yeast and sugar will escape sometimes into the
stone or wooden diffussor and can clog it. Usually a vinagar bath will fix this.

I could understand that.
But, If you use a bubble counter, it would be impossible to have anything but pure CO2 enter the stone. Eventually deposits from the tank can form, but it is unlikely as it should (theoretically) be forcing the aquarium water away from the stone at all times. The wooden stones will generally produce a superfine bubble, much better than ceramic or "stone" airstones. The only airstone i have found that rivals a wooden stone (for the size of bubbles) is the RENA airstone (http://www.bestpetsupply.com/brands/...Pharm/1617.asp). -- Matt C. http://home.comcast.net/~amgock "www.Fish-Forums.com" wrote in message ...

The airstone was about a dollar. Right now, for the results that I am getting (which are pretty cool, frankly) the wooden airstone will do until I can arrange something else. Thanks, though. I will be experimenting with more stuff soon. -- Martin Moran omNO.SPAMmoran at telusplanet dot net Beaumont, Alberta remove "no.spam" on replies http://www.telusplanet.net/public/ommoran/publickey.txt "When you're caffeinated, all is right with the world" PGP Public Key Fingerprint: CEF6 48D8 73FC 2A36 3287 FC20 CAEC 75D1 9C58 B861 |

I will be experimenting with more stuff soon. After a couple of years of experimenting with various DIY CO2 diffusion setups, I eventually settled with using the diffuser which comes with the Hagen "Plant-Gro CO2 Natural System." You can buy the diffuser separately from the whole system. Mine works great in my 29gal, heavily planted tank. I didn't see your original post so I don't know how large your tank is, but you should be able to use two or more diffusers as required. |
