Really you guys need to start to get a grip of this hobby.
1. Promoting the API master test kit over the API test strips is nonsense who cares really and what do you ever do with the information you gain. I have only ever used the test strips. Zero Nitrites and zero Nitrates = zero Ammonia. Move on.
2. "Seriously Fish" Neon Tetra pH 4-7.5 hardness 18-215ppm. That means a Neon Tetra will live in any freshwater tank regardless of its chemistry.
So therefore, as I have been looking at " Seriously Fish " every fish I have looked at will live in any tank that has fresh water, so please explain why test for anything. There is no point. " Seriously Fish " says it will survive in your tank.
Why spend money on a test kit that will tell you something about your tank. But then you will go to, "Seriously Fish" and it will say that's fine your fish will survive anyhow, so why test in the first place.
