I have been running my tank without a skimmer for almost 9 months. There was some Red Turf algae growing but that algae came on a piece of liverock that I bought. The algae went away after I used Chemiclean and never came back. All I have is a heater, powerhead in the tank.
I do weekly water changes and feed the fish very little. All my fish and corals have been doing very well.
