These corals have been growing quite well for some time but I am having trouble keeping cyno from settling on the ends of certain corals. I blow it off but the damage is done. I am noticing a couple are starting to whiten out too. My Pink Floyd especially. Only change is lighting. I had an ATI powermodule that had 2 bulbs not burning. I fixed it and par increased some but not a whole lot. Par is around 320 where these corals are right now. Alk is 8.2 steady. Cal is 450 steady. Nitrates are about 50 and pho’s. Is .20.
Good flow in tank.
Not all corals are doing this at all.
Any ideas?
