I've just planted my first tank and I had a question about setting up a DIY CO2
Pertinent info: The tank is a 75 gal
SeaClear System II (I got a good deal on a used one), so it's got the filter stuff sectioned off in the back (essentially overflow goes through a prefilter which overflows onto a trickle tray over bioballs, which then gets pumped from a 350 gph
pump out a manifold with several holes to the main tank). So really it's a ~60 gal
main tank with ~15 gal
in the back compartment. I've got 2x40W Chroma50 and 2x40W 6500K Daylight bulbs, and I just planted it today with Vallisneria spiralis, Rotala indica, Hygrophila difformis, and Cryptocoryne wendtii, and started fishless cycling it with ammonia.
So, back to the question, I'm planning on setting up 2 2L bottles of yeast culture. The tank came with an airline tube connected into the filter system near the base of the bioball compartment. It's called the Air Injection Nozzle in the instructions, to connect to an air pump to increase aeration to the bioballs if you want. However, I think I read on-line that some people inject their DIY CO2
into a bioball compartment in their their cannister to diffuse the CO2
, so I thought maybe I could do something similar and connect my yeast bottles to the Air Injection Nozzle. Does this sound like a good idea or 1) the bioballs won't really diffuse the CO2
much, or 2) the CO2
may actually hurt my bacterial filter? If it did work, it would be great because there would be no need for an eyesore of a diffusor in the main tank (currently there's no equipment in the main tank) and the CO2
-enriched water would being getting pumped throughout the tank.
I guess I can try it and see how much CO2
is dissolving. I have very soft water (I was planning on adding limestone to increase KH
), so I should be able to tell pretty easily from the pH drop if it's working. If not, what type of diffusor do you recommend?
Sorry for such a long message. Thanks for your help.
