So i have been fighting this for the last 2 or so months and cant seem to get a grip on it. I have tested my phosphate and nitrate and both are not high at all. I think nitrate was about 5 or less and phosphate was about .01. I have siphoned out the excess and also scrubbed the rocks in places then do a water change. Also have tried red slime remover and didnt seem to help. Does anybody have other things i can do to get rid of this stuff? I have had this in other thanks before but has always gone away.
