water Test kit?

[flame82]

i have two different bands of test kits and one works pretty good and the other i will never again waste my money on. i would like to know what a good kit to buy that gives nice clear reading and doesnt have three stinkin shades of the same color which all look about the same. i would like to find a good test kit that reads accurate and is easy to read with different color for each ppm.

I like the Fast Test marine test kit best. There's also Salifert.
