I normally run my sump light for 6-8 hours each night as the main tank light is off. I also keep plants in my sump and I used to keep shrimps. I put the light back in last week and no more diatom in main tank.
does this make any sense? The filter socks captures all the feces/food and I replace the filter socks once a week, and not even the sump has diatom.
