I have a slight problem with nuissence red algae. I have tried more current, adding a refugium with cheto, have a skimmer and DO NOT over feed. I am wondering if it is possible that I do not have enough LR in my tank to filter the nitrates in the system which in turn will lead to more freakin algae. I only have about 30 lbs in a 50 gallon tank. I have made arrangements to buy 25 lbs but will this be enough. I really do not like the look of an over stocked Rock reef so i wanted to keep my LR to a max of 50lbs. any ideas? am i right or are there other solutions to my problem.
