I'm experiencing less and less algae in the aquarium, added a few sps frags, but my millepora has withdrawn it's polyps. Any idea why? Nothing is measuring out bad, and it seems to be growing. Could it be a result from one of my angels?
Anyways, my sump where the wather comes from the scrubber is filled with foam ontop. (almost like skimming) meaning it's probably alot of protein in my water, and I got heavy growth on my glass all of a sudden. (Have to lcean once a day). I've also started to getting brown slime on sand and while thinner, brownish short hairs on the rock. (1-2cm at longest).
Master Algae, please explain? Scrubber is growing good, flow is good, so what is causing this?
