I have been having a recent problem with red algae. My nitrates have always been around 20 and phosphates are 0. I only have one fish in my tank. Every 3 days I have to stir up the gravel to get rid of the red algae. Does this upset the benificial bacteria in the sand. I have never had this problem before. I only feed my fish once a day. Would getting a protein skimmer help reduce it. I have an emporer power filter and the tank is 40 gallons. Thanks
