for this batch, add an airstone for the fishes. best to hook up the airpump to a timer that on after the lights out and plants no longer take in co2. timer off airpump when lights come on the next day. |

this is the hazard of 24/7 co2 injection using diy co2. those with solenoids time the co2 injection according to lights on periods (on half to 1 hr before lights on and off half to 1hr before lights off). this will ensure that the water is co2 saturated when lights come on so that the photosynthesis process get a real good kickstart. co2 off earlier so that the plants will use up most of the co2 in the water before the lights go off. |
