Two weeks ago, I dosed my new tank with TSS+. I have a betta and a neon tetra in it at the moment. (I know that neon tetras need 5+ bc they are shoalers, but it was never the plan to even have it. After the tank is established, it is going to be a species only tank with just neon tetras.) But anyways, after two weeks, the nitrate level is only at 5PPM and the ammonia is at 4PPM and the nitrite is at 5PPM. What should I do??
