I read about the PRIME conditioner before. I was referred to a brand called AmQuel Plus. This is what I've been using so far. I initially had a normal conditioner and then went with the AmQuel Plus. Before doing my morning water change, I ran the tests and my results were: ammonia .25, nitrite .25, nitrate 0ppm. My tiger barb is sticking around the top of the tank, going belly up for a second, then flipping back over but still at the top. I know this isn't normal behavior. Has anyone else experienced this before? Also, my wife wanted me to purchase this set of chemicals called Microbe-Lift. I did, but have yet to use them but everyone thinks that the guy, who said I should use it, is a jerk and a lousy specialist. Has anyone had any experience with that product? It contains three bottles: the aquatic stress relief, the "special blend" (which claims to contain a complete ecosystem in a bottle), and NITE-OUT II (used to rapidly reduce ammonia and nitrites). The NITE-OUT II says to use it until the ammonia reading is below .6ppm...which it already is. I'm not sure if I should start using it or not...HELP!!
