My fish only with life rock tank has been up for about 9weeks now and the lr has cycled, all test for water are fine green algae has come and gone Every thing is fine except I have this Scum layer on the surface of my water. It looks like a cross between pieces of algae some debris from the lr and also some dust from my crushed coral bottom. Since I am a fish only tank I have a canister filter, protein skimmer and power heads no skimmer for a wet/dry. How do I get this off the surface of my water? I will attempt to attach a pic.
