Diatoms at 2 months is normal. I am going through that now. I clean the glass daily and turkey baste the rocks. Also rinse my passive carbon every 2 days. This seems to help and the diatoms look to be in recession. If its green then you may be dealing with algae. Check your PO4 and reduce your photo period and/or intensity, if you don't have corals yet.

...and where's your tank journal? It's a new requirement on Canreef!
