I have posted a few times in the past about my lack of coraline algea growth in my 7 month old 55 gallon tank. I have around 60# of live rock, half I bought from Drs Foster and half from my LFS
. I have developed some growth on a couple of pieces and on the powerhead/filter areas, but not really any coraline algea growth on my rocks. I have a wet/dry filter with a Octopus skimmer and Nova T5 lights. I just relized that my Pincushion Urchin ate a large section on one of my pieces. Has this been my problem the whole time. Is the urchin eating it faster than I can grow it? Some of my LFS
liverock looks white and bleached to me but water parameters look good. Any help would be great.
