Re: Co2 Dilemma
I am behind (18 days) on reading APD due to a Fish Show and college
finals in the same time frame, so sorry if someone has already given the
same solution to this problem. When I had this problem over a year
ago, I set up a air pump and an air stone with a timer to run only at
night when the lights were off. This worked great when I needed it. I
use the 2L bottle system and there is no shutting off at night. JiM C.

I have been having the same exact problems, so I hope you get a lot of
responses as to what could be causing this.
I know some people turn off their CO2 at night, but that supposedly
large swings in the pH, which, of course, is not recommended. I have
a temporary "work-around" solution, which evolves adjusting a filter
a little more toward the water surface. I know I am probably losing some
by doing this, but it keeps the fish from struggling. My Kh and pH
also indicate a safe level of CO2 (so does my LaMotte CO2 test kit), but
would never know it from how the fish are behaving. I am beginning to
believe it is more of an O2 deficiency than a CO2 surplus.
Any thoughts from the List would be much appreciated.
