Hey everyone, I am new to this site and was hoping to gain some knowledge on reef keeping. I've had a 55 gal. saltwater aquarium for over 8 years now, but am new to reef keeping....I currently have a green spotted puffer, a clown, curly q anemone and a colony of...u guessed it -- 21 pink clove polyps. I have had them for a few months now and they have not spread or multiplied yet. My calcium is at 450, alkalinity of 11, salinity of 1.022-23 and ph of 8.4. My nitrates are currently at 20 but I'm still lowering. Unaware of Mg level. I have a 10,000k and actinic that end up giving out 2 watts per gallon for about 12 hours a day. Any advice on how to make these pink clove polyps flourish and/or spread throughout the tank? Thanks guys!
