Well, at long last I may finally be getting my tanks filled and my CO2
system set up.
It's taken far longer than I expected.
So, I have a question about CO2
and lighting: to keep algae under control, I've run a split photo-period: on from 8AM-noon, off from noon-4PM, and on from 4-8PM (4-4-4). It's worked well to keep the worst algae under control.
Do I need to stop doing that and go back to a continuous 8-hour lights on, or will the CO2
be effective if I set its timer to 4-4-4?
