I have a test kit that is over 5 years old. The drops are all in sealed bottles for various tests... ph
, alkaline, ammonia, nitrites, nitrates.. it is a Marine Lab 5-in-1 kit.
test seems to be right on, but I'm worried about the other tests. The ammonia test has shown a murkie green color (equates to 0.5ppm on the test chart) every single time I tested. The Nitrite test always comes up a pale yellowish color, which isn't even on the chart (aqua color = 0, and purple color = 1 & above ppm
My tank has been going for a couple months now, with Live Rock, cleaning crew, and a couple damsels. I have had nothing die, fish look healthy, and the cleaning crew is always on the move.
Is it time to buy a new test kit?
