OK, just did like a 15% water change. First I tested my tap water and that is only like 5% nitrate thankfully. I was envisioning having to buy special water. Yikes. Or carting it over from someone else's house LOL. Then I came here and see that 50% is more like it. OK off I go. I am testing it again and it doesnt look good. Does anyone know if you have to shake the #2 solution for 30 seconds every time if you are doing test after test? All of this shaking is killing me hehe.

Thanks again,
Carole
