So, I have been battling cyano for the last couple of months. It all began when my BTA formally introduced himself to one of my Koralia's one night. Needless to say I woke up to more soup that an aquarium. This caused a nutrient spike and got me to where I am today. After the "Incident" I did two, 15% a week water changes to get the nitrates back in the ballpark. All with RO/DI water. I added a skimmer (That I needed anyway) and have been skimming wet since it was broken in. I get about a cup of tea to coffee colored skim out every day. I ditched my wet / dry in favor of a seven gallon fuge with 3" sand, LR, & cheato. I change out my filter sock every day for a clean one. I ditched my old power compacts for a new four bulb T-5 fixture. The lights have been cut back to a 10 hr cycle. and the fuge light is on a 14 hr reverse cycle. I have been manually removing the cyano every other day with a turkey baster. I cut my feedings for the coral (Sunpolyps, trumpets) and the fish in half, every other and once a day respectively, and never more then they can eat in a couple of minutes. I have two small (300 GPH) return pumps and two Koralia nano's for flow. The cyano is primarily on the sand but some on the rock work. My water pram's are (double checked at a LFS today) ph 8.4, Ammonia 0.0, nitrite 0.0, nitrate 0.0, phosphate 0.0, calcium 460, dkh 12, mag 1300. I do not want to medicate the tank, but if things don't get better soon I just may. Even though at this juncture I for the life of me can't think of an underlying problem that I haven't addressed. I "Think" I am doing everything to make it go away short of a blackout but it still returns. I know I am probably a little overstocked on fish but they are all small (two clowns 1.5" ea, yellow watchman maybe 2.5", McCoskers wrasse 3" and a red firefish 3") all my coral are still small bought as frags. And just the usual suspects for CUC. I did fill out the Reef Cleaners form and I am waiting for them to get back with me to see if I have enough. Quite frankly, I am at my wits end and I am taking suggestions.
