I have a 90 gallon mixed reef tank with 5 fish and a protein skimmer. When I change 15 gal/week I have no algae issues, but slow coral growth. When I change 15 gal every other week I start getting hair algae on my rocks.
What fish and do you have corals? That will help figure out the schedule.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
