HI ! Does anyone know if there any impact on SPS , LPS and fish etc if i keep my moonlight on throughout the night ?
Will this stress the live stocks and cause more algae ?
You need to have a skimmer when using biopellet . Purpose of the skimmer is to skim out the wastes n excess bacteria created by the Biopellets . Without a skimmer algae diatoms even red slime will outbreak and i have experience this when my skimmer was off or faulty for a week.
