A few people mentioned that over at the SC forums. It's weird cause I do it to keep the gnats out actually. I usually run hempy and although I get algae it's never been a prob and no gnats.That perlite will be the death of you. Get this if you want a top dressing. Perlite attracts green algae and attracts gnats like a mofo
Bawse!
Got me second guessing now though...
