agreed with jsker. its a big fat ugly phase. check the major params.Thank was setup in May
bio is bio, theres different methods
But, im on a lil different approach, id bombard that thing with good diverse bacteria, mb7 AND dr t or you fav brand,(it will reduce Po, No to, what a pellet reactor does too), and air, check the skimmer outside air n stuff. look at a poly pad for the po and no(its a gfo basically) or GFO, and itll pull some of nitrate out too and silicate as well in a slightly higher flow area.. run carbon in a high flow area or reactor too.
im a big refugium guy. think about macros.
try to out compete the yuck for the food it needs.
a lot to swallow i know but keep in mind make those additions slowly. you dont want to strip the water too hard of nutrients or the corals will suffer. Mine hate it, i dont use it.
I had a major clean up too, and I became a fan of the $60 canister, ran carbon and floss and sponje. I break it out still when I aqua scape clean big or just make a general mess.
you can put gfo in too, I dont use it but still have a bottle. somewhere, I think.

. Go by the look of you tank and your tests. Once you know what your ideal look is and test are, then you will not have to test as often, but still test just to make sure.
a gfo(esp for poss nef silicates) or nitrate reducer, poly pad etc same thing, SLOWLY.
