My tank is about 5 months old and is kind of drowning in GHA. I didn't have much of a clean up crew until very recently so that's one obvious problem but I think another underlying problem is that much of the rock I used is both very dense and had a ton of organics in it. I thought one useful change would be to get rid of lots of that rock and exchange it for higher quality more porous and clean rock. The denser pieces seem to grow it disproporionatly fast despite no measurable phosphate in the water and having trouble going GHA on an ATS. This implies to me the phosphates are local to the rock.
I'll continue hydrogen peroxide treating individual rocks each day but if I decide to change some rock would dry rock be better or established "cured" rock be better. I'm going back and forth.
