I have a relatively new reef set up. It has been running about 7 months. I had a nice growth of coralline algae on the live rock & rear glass, etc. I initially had a problem with diatoms, which eventually subsided, followed by a cyno bloom. The cyno algae is now beginning to fade, and I am now seeing an increase in hair algae. Also, some of the coralline algae is starting to turn white. Is this a natural progression in a newer set-up or am I missing something? My levels are as follows: Ammonia-0, nitrite-0, nitrate-0, Ph-8.15, Sp. Gr. 1.025, Temp. 77.9, dKH-9, Calcium-380. Phosphate is about 0.03 but I'm not sure that I trust the test results. 54G RR aquarium, 130W PC lighting, sump, 2 Koralia 2's, Aqua C Remora skimmer, 40 lbs LR.
