Will someone please share the gosh darn secret to getting rid of green algae. If I do a water change every week it's gone, no problems. But I don't have the time. My tank is only thirty gallons with no sump. Hob skimmer that skims okay but not great. I run chemipure elite or phosban sometimes in the hob filter to try to alleviate the algae but it doesn't help. Each water change I'll scrub the algae off and do a water change and it'll stay gone for like a week and a half and come back. Is carbon in a media reactor, hob, the way to get rid of it for good? To answer your first question, My parameters are normal but yes my phosphate are high, and would be even higher if the algae wasn't using it to grow. Please fill me in.
