Hey everybody, I have had a 55 gallon Saltwater tank for about three weeks now and it is taking control of my life slowly. I have been doing alot of reading and am getting educated on the whole ecosystem. Here is my setup so far, let me know if you can point out some obvious mistakes. I started out with 4 damsel fish, 20lbs of live rock, a few snails, a starfish, I have 1 powerhead a heater, UV lights, Biowheel (which I am replacing asap). I started with live bacteria, changing 10% water a week, temp. around 75, Purpleup calcium once per day. Please pick me apart I need to know what I am doing wrong. Any suggestions on a good filter?
