I have had a 55-gallon salt-water tank set up now for two and a half months, but it still hasn't finished cycling. The ammonia went up and came down, the nitrites went up and stayed up, they have been between 3 and 6 since July 24 (when incidentally one clown fish died, sorry to say). I've been doing water changes, between 12 and 18 gallons every few days, but it doesn't seem to help at all. I still have two damsels, but they're NOT HAPPY! I know now that I should not have used fish to cycle my tank, but it's too late now and I really need help. I've heard of a product called Stability by Seachem, does anyone know if this is a good idea?
I'm at my wits end and really don't know what to do; please give me some advice.
P.S. I also have a bunch of brown algae growing constantly, which is annoying, but not my main concern.
