Woke up this morning and I have ich in my tank. I cycled 3 weeks ago I did my test this morning amonias 0 nitrates 0 but my ph is at 8.0 my saltity is a 1.023 just looked at temperature and it is at 82. I have a 120 gallon saltwater tank with 2 catfish 4 turbo snails 1 rock beauty anglefish, 1 blue tang 1 yellow tang and 2 clowns(nemo) What should I do to treat this? Anything with the saltity or ph? Are should I just treat the ich? Thank you anyone for any help.
