hello everyone. so I setup an algae reactor, using a TLF reactor and red/ blue led grow lights from amazon. I set it up three weeks ago this Sunday. I run the light 16 hours a day. I check the cheato every day and no growth, I have kids in it already as I can see them swimming around but no growth, is this normal ? last time I checked my nutrients my nitrates were undetectable, my phosphates are at .25 . what am I doing wrong ?
