I was wondering if it is possible to have a test kit that could be no good. I purchased the drop test kit when i first got my tank. my ph and ammonia would show change over time, but the nitrite and nitrate have never changed. I tried the test strips and it showed a slit amount of nitrate.
Also, what do you guys prefer, the strips or the drops.
