Welcome to FishLore! Let's see if we can get you on track. First off, tell us what size tank you have and what fish you have. Next, if you don't already have one, I'd strongly suggest you get a
Aquarium Pharmaceuticals master test kit. This master test kit is very economical compared to other tests, and it's accurate. If you do have one, please post your ammonia, nitrite, and nitrate levels. Once you tell us a little more about your tank, we can start to help you. It's great to have you with us, and we look forward to helping you get your tank on track!
