What Test kit do you use??
Ive been pretty lazy to do research on a more exact test kit. I think JPTC had a thread about some test kit that get real low params... I think it was a pond test kit that worked extremely well
16 of your 21 tanks........ what do you run a fish store?? if not, might as well make some cash. Good Lord thats a lot of tankYou should start a new web site that states "Monster Tank Keepers"
