I know this has been discussed to death, but short of chemicals, I am running out of ideas. My 55g FOWLR is a year and a half old. A month or so ago, I developed a little cyano. Daylights off for 3 days got rid of it, and I replaced my GFO. Had a sudden overrun of green hair algae, cyano and short brown hair algae I cannot get rid of. No changes to the tank at all. Doing 10 gal water changes weekly, replaced the lights etc. Salinity 1.025, temp 77 +- .1, nitrates <10, alk 10, calcium 400, phosphates undetectable. Fresh Rowaphos GFO. I have a ton of pineapple sponges all over. Feeding Thera+ and nori. Water is RO/DI, replaced resin, TDS 0.
Have to clean glass daily due to green hard algae film. I'm about ready to just tear it down and start over... As far as bio load, 1 yellow tang, 1 spotted puffer, 2 "caramel", 1 clarkii and one ocellaris clown and 2 blue and gold damsels. Running HOB skimmer that has been doing a good job.
As I say, it started suddenly with nothing else changing and am at a loss.
Thanks
