Does anybody know the expected life for AP test kits? Mine are about 3 years old (at least that's how long I've had them, no telling how old they actually are). Anyways, I just moved, put all new water in my tank (1 clown and some corals and inverts) very lightly loaded. I had been kinda slack on testing prior to the move. Been set up for 3 weeks now Ammonia, Nitrite and Nitrate have read 0 everyday. NOt that I'm complaining, I just don't know if I believe it. I expected an ammonia spike from LR
die off from the move. And I know I feed sparingly, but I still can't believe my Nitrates are 0.
