Had the oddest thing happen when testing water just now; My nitrites seemed to have spiked to .2, first time I've had a reading on my nitrite test since I cycled the tank about 2 years ago. Other facts:
I'm treating the tank with red slime remover (I know differing opinions on bandaiding the problem and fixing it) and just did a 20% water change yesterday. I expected lower ph
, but High Nitrites kinda threw me.
Any ideas, should I be worried? I just redosed the red slime remover (after the test) so I can't do another water change for a few days.
Fish look fine btw
