Help with CO2 Tank System and Eclipse Filter/Hood
I purchased a 5lb tank of CO2 and a regulator. I cut a small hole in
the bottom of my incoming filter pipe. I ran a hose from the regulator to the bottom of the intake pipe. The pipe is clear and I can tell I've got about 2-3 bubbles per second CO2. The intake pipe goes through impeller - sprayed out onto mechanical filter and then into biowheel. Does this sound like an adequate CO2 setup? Do you think the bubbles will get diffused correctly in the impeller? On a 20g tank, could someone estimate the ph drop I might see at the rate of CO2 I'm putting in? Thanks |

i found that removing the biowheel raised the co2 level by about 5ppm. i was
using diy but with the same approach as you on a system 3. your co2 bottle will do better. good luck jtm -- Remove NOSPAM for email replies "Bill Beam" wrote in message ...

The bubble rate you have set sounds high to me for a 20 gal. I run just
slightly less and 1 bubble per second on my 55 gallon tank. but you have the bio wheel which will help you to lose a lot of the co2 you inject. I would suggest you remove it. Watch your pH level closely initially and use this calculator to calculate your co2 level. Also watch for gasping fish - a sign of too much co2. http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm -- Bob Alston http://members.cox.net/tulsaalstons/ "Bill Beam" wrote in message ...

Looks like after several hours of this setup, I've got - KH at 4d, PH at 6.9 for a CO2 level of nearly 15. I think that's probably OK according to the chart on the link you gave me. Question about the biowheel - if I take it out will I see a spike in ammonia/nitrites? |

Maybe. Depends on how well established the rest of your filter is. If the
filter media has been in place for a while, then I wouldn't worry about removing the biowheel. Remember, lots of hang-on-the-back filters work just fine without bio-wheels.

Guess I'd have to stop that. Guess I could just wash off the debris and put it back in. Do you think so? Thx again. |

That should work. Best if you wash it off in dechlorinated water. I prev
had an dual-bio-wheel filter so I could alternate which filter media I rinsed and which I had to replace.

Make a small hole big enough to shake/dump away the active carbon.
Then refill with some sort of high surface area material - small lavarock or anythying ceramic you can find in the pet store that is mean to be a place for nitryifying bacteria to grow. Takes very little to fill that bag. --Nikolay |
