im not a hydro guy so i cant say for sure but brownish slime sounds sort of like root rot to me.. or at least the begining maybe.look at the link and see if you have the signs.Hey guys . I mix my nutes in a 25 gal res. I have noticed that there is a brownish slime growing on my airstones and in my res in general. Could it be one of the nutes? Any ideas?
check that link out i think it applys to your situation. peroxide seems like a good solution.also hottest water you can stand when you rinse it out.Peroxide seems to react with whatever it is . So i am doing a peroxide wash . Then gonna try to mix up 1/2 a batch and see what i get . Hopefully peroxide treatment will be enough. Im sooo broke.
np..nice to see you fixed it.Thanks . Thats what i tried . Seems good so far.
