Hello again,
I was getting ready to add some fish this afternoon by performing a large water change (around 90%) to get rid of all remaining nitrates, but even after this huge water change my nitrate levels do not seem to have come down at all and are still around 80ppm.
What’s happening? I’ve retested several times, and made sure I thoroughly shook the test liquid as the instructions said for over a minute, but all results are coming back as 80ppm.
Ammonia and nitrite levels are at 0, only the nitrate is letting me down.
