Hi,
Just repeating what I wrote in an earlier thread; I have a 100g tank, AM1000 + powerhead misting CO2 through a spray bar into the thickest parts of my planted tank.
CO2 comes on at 1pm and goes off at 11pm.
Lights come on at 2pm and go off at 12am.
I have been slowly tweaking my CO2.
At about 9pm, my fish start heading for the surface.
I understand that plants do most of their growing (i.e. CO2 utilisation) during the first 8-9 hours of the photoperiod. So, this seems to coincide with when my fish start gasping. Am I right to assume that my CO2 levels are probably pretty good between 1pm and 9pm, and then simply start to climb into the danger zone once plant utilisation slows down at 9pm?
I can either dial the CO2 down slightly, or, increase surface turbulence. I'm leaning towards the former as I don't want to waste CO2.
My tank is very understocked, by the way, so it can't be an oxygen shortage.
Scott.
