Been thinking for months about jumping the gun and getting into all this SPS madness and I've finally decided to do it. My buddy Derrick started me off with some SPS starter frags, and yesterday I picked up an acro for my tank. My system has been up for a while, lots of goodies growing. Coraline algae has become a pain to take care of in my tank, should I just scrape it off so that the SPS get enough calcium? And anyone got some tips they can throw at me so I don't get into a neverending black hole of SPS death?
