Thanks Juiceman. I have some coral frenzy and will try some feedings to see if they recover.
Michae52, I have been dosing iron and magnesium. I did not know about manganese, unless that was a typo. Are there readily available test kits for manganese?
PBNJ, yeah, I have a pooping hippo, sailfin, and yellow tang. Hoping their mess is my goniopora's gain. It was doing just fine until the cyano outbreak... now the recovery part is the issue. It probably speaks volumes about my tank not being to support goniopora if it can't recover quickly. That threshold was probably just keeping it alive in my tank, and one slip and it'll go spiraling down.
Let's see if I can strike a delicate balance between enough food for the goniopora's in the water but a low nutrient environmental enough for my SPS. I think this is an uphill battle.
On that note, again, if anybody has a successful goniopora tank, with the parameters in the first post, let me know so I can send the frags your way for a promise of a frag back when it is better off.
