The reason I wanted to run lighting 24/7 is because sump/fuge also has cheato algae in it. I thought the benefits were: 1) Premium Aaquatics said the algae would grow faster under 24/7, and I'm aslo trying to use the cheato as nutrient export, so win-win. 2) the algae would always be an oxygen producer since it always under light. 3) ph wouldn't fluctuate as much since the algae is under 24/7 lighting.
But the problem is that my DSB is underneath the cheato, and since most of the organisms in a DSB come out at night, I wasn't sure if that would reduce or even kill the effiency of the DSB.
