Night time hypoxia?
Do any of you folks worry about hypoxia in fish in a heavily planted tank at night... do you run an air stone at night for this?
My set up: heavily planted 29 gallon, 110 watts PC, 1.5 - 2 bbs/sec CO2 with Reactor 2000 diffusor, 7 kH, pH 7.8 (maybe really 7.4) in the AM, drops to 6.9 pH where CO2 shuts off with Milwaukee controller. CO2 system not run in the PM (on a timer synced to lights). I am running a Biowheel now (I know I lose some CO2), which I will leave for the moment for night time surface agitation.
