Hey guys I have recently (4 months ago) acquired a 45 reef tank with live sand and live rock. I have a canister filter, a 26 watt florescent light tube, and koralia 4 powerhead in my tank. After 2 months of treatment I put 2 little clownfish in there with 5 nassaruis snails. After 2 more months I can see a buildup of spots of algae on the wall of the tank (i clean them up with paper towel). Now I can see the the rocks changing color (because of the algea). My friend says its normal.
But here it is. Do I need a protien skimmer?
