My tank has formed some kind of white spots all over the tank, the spots are hard and look like big pieces of salt and they stick to the walls of the tank. I have had them for weeks now and i dont believe its ich, what could it be????
Sounds like small calcerous tube worms, if you look closely do they have a spiral shape? you should also see the very small crown of a tube worm poking out from time to time. They are neither good nor bad, but are very common in FOWLR and Reef tanks
