If anyone can offer advice as to how to identify this algae and then treat it I would be extremely grateful. The tank is 1&1/2 years old. It is 125gallon I use a 40g breeder sump I absolutely cannot get rid of this algae. I scrape the tank everyday and everyday it grows back. I use rODI water and an 8.4 ph buffer I add and do water changes constantly trying to rid myself of it and nothing works . If I don’t scrub the walls for a couple days it’s overgrown like something from I am legend. If anything appears to be wrong with my setup I post in pictures please I welcome criticism. I used to have a 13w uv sterilizer that did nothing.
