Hi,
I have been tweaking my co2 injection, and now have a nice greeny/yellow at start of photoperiod.
The problem is that 3hrs or so into the photoperiod the fish are starting to show signs of stress i.e a few are gasping at the surface.
I must state that the co2 switches on at 2hrs before lights on.
Now if I now turn the co2 off it will mean 4hrs with lights on and co2 off.
Would the plants have,and continue to have, enough co2 when the co2 switches off?
