Hi there!
Can you give us a little more info. First....how big is the tank in gallons...or please let us know if your dimensions you listed are in meters (hopefully) or feet? Can you tell us what brand of aquarium you have? Also, don't say your water tests "fine..." we need to know your Ammonia level, pH level, Nitrite, Nitrate, Temperature, and Salinity to start with. How much live rock is in the tank, and what sort of filtration do you use?

Also, a picture is worth a thousand words.
What are you using for top off water?
What kind of water are you using for water changes?
