I am new to this site and after reviewing it thought that someone might be able to help me. I got a 55 gallon salt water tank from a firend and set it up the end of December 2006. I rinsed everything out and cleaned it up to have a fresh start. I placed the crushed coral in the bottom with my bubble bar. Put in my two heaters and put in my biowheel 330, filled with saltwater and also put in 1 1/2 gallons of saltwater from my friends very healthy tank. I let this run for 9 or so days and then put in 6 damsels which Petco recommended. I lost 4 the first week in a half and just lost my last one on Sunday. I did a 20% water change a few weeks ago and did about a 4 gallon water change 4 days ago. My tank is reading unsafe for all the ammonia nitrates and nitrates and my PH is 7.8 I am adding a little buffer for the Ph. I bought a piece of live rock a week ago and don't know what else to do. I now have a full tank with no fish just a brown algae covering everything. What is happening and is this normal. Please someone help.
