In the last month or so there has been a huge outbreak of brown hair algae. We have been trying everything to remove it. The tank is 1 year old, have reduced feeding to 3 times a week, Phosphates and nitrates are undetectable, manually removing algae every couple of days. Our bio load is pretty high but the skimmer is way over sized and has been doing its job. The tank is by a window but can't be moved. we have a good cleanup crew. Any help is greatly appreciated.
