What are your water parameters, specifically nitrate and phosphate? How much flow do you have? What kind of water are you using?

Ph-8.4
ammonia-0
Nitrite-0
Nitrate-5.0-10
phosphate was tested a couple of days ago by my lfs and it was fine, but i dont know exactly what it was.
As far as flow I have two sea swirls that give me a good amount of flow for a 90 gal.
I top off with D.I. (I also add aragamilk to the top off water).

Your parameters look good. I had that problem in one tank and the only thing that worked after stabilizing the water quality was less light and better
water circulation. The chemical treatments worked for me but the slim would come back in 10-14 days until I dialed back my lights 10% and added a powerhead to increase water flow in the area that it was accumulating.
