I have been fighting a hair algae problem in my tank for a couple months now, tried snails, limited light, scrubbing the rock and it keeps coming back. I am thinking of adding a Micro Algae Reactor as I don't have space for a Refugium. I see there are many DIY options and a couple products from Aquatic Warehouse, Skimz and MD but wanted to get other opinions before I went this route or a chemical route.
