I agree with Geoff here, just the early stages of Your tank, will go away soonGeoff said:do not get any more snails for now. you are in the middle of the diatom bloom. this will go away almost overnight in a few weeks. if you get a bunch of snails they will just die when their food source goes away. this is that whole sit on your hands thing and not put anything in the tank for at least a month thing.
Cyano is a different story than Diatomsfchidsey said:I have heard that when you have cyano dont do a water change until the bateria has died off. anybody? I also say no more snails let the bloom run it's course.
