So I have a 75g, and I can never get rid of my algae completely. And now I have a blossoming of ditaoms on my sand and cynical in my sump.
I want to completely redo my refugeium, adding mangroves and just someway better to extract nutrients.
My parms are fine, everything is in order. I'll post exact stats when I get home from work. My corals are thriving and growing, I use ro
water and recently dropped 250$ on a new 5 stages unit from bulk reef supply and I still have these issues. I've tested for phosphates and I still have nothing showing on that.
But I really just want clean sand, I have hundreds of snails but like 1 hermit crab. (He's an unknown species that has done very well, I want to invest to more blue legs but he's killed them all, very aggressive but reef safe white hermit crab with big sorta fuzzy claws and completely blue eye stalk/ feelers, he's going in the revamped sump)
Also every time I had top off water, my skimmer goes nuts, do I have it set to high? I do 12% water changes every week in the dot
It's a 75g, with a 20g sump, it's been set up for two years so I know something is up with my water, but I'm stumped.
