algae blooms

[BC564]

I started a 72 gal bow front approx. 3 months ago and went through the same thing plus had hair algae and cyano. I used algae magic on the hair algae and a few days later added a phosban reactor. It cleared it up and have not had hair algae or brownish algae since... My tank is bare bottom so I suck up the deitrius weekly and do a 5 gallon water change at the same time. I like doing the 5 gallon weekly as opposed to 20 monthly both for ease and for fresh salt water added in smaller amounts. I had a pretty small cleaner crew when I started it up and have since added lots to the crew.

Also what kind of skimmer do you have and has it been pulling lots out of your water?
