I have a new 27 tank it has been cycled, tested the water all levels were good so added fish. Fish got ich, this killed all 4 tetras. We treated as recommended by the fish store, 1st treatment was fine, 2nd treatment, lost one guppy. Then did 25% water change, I just tested the levels and nitrates and nitrites are through the roof.
pH is 7.5 and ammonia is 0 - 0.6 (can't really tell if there is a bit of color there.) What do I do? We haven't been having any luck with this and I really need some help.
