I like this idea of having a thread about ones tank so I thought I would add mine into this great list. Currently I am (still) in the process of a larger upgrade so this has been a temp home for my inhabitants. It's just a standard 75, I have it lit with 4 54w T5's. skimmed with an ASM G2. I started up my first cal reactor about 4 months ago and have had a tough time getting it right. my cal stays about 410 but my alk is sometimes up to 16dkh. I have been having a major problem in the past few weeks with several large SPS colonies bleaching and some smaller LPS colonies melting away that i attributed to my high alk. to help with that i did 2 30gal water changes in 5 days and have since seen my sps coloring back up. here are a few older shots that I'm sure i have shown somewhere. right now the tank is in no way photo ready.
