Hi! I need help figuring out what this Algae is, it has been in my tank for a while and I thought it was my lights. However, it wasn't because I got rid of my junky LEDS and got T5's. I have been running GFO for about 8 months now and still have this Algae in my tank. Its like white hair algae? But I do not know... It has a brown base and then like a white hair. I have not found anything online about it...
I did the 3 days lights out and it helped the glass and the powerheads/overflow. But the rocks stayed the same and 2 weeks later it came back. Plus I only feed 1 block of mysis every other day and seaweed on off stays. So I definitely don't think it is phosphates.
Any ideas? Or tricks to get rid of this?
