I do my water tests every week and today I found out that the ammonia ( NO3 and NO2) is extremely high. Before it was always 0 and I don’t know what I did wrong and how I can fix it... I just cleaned the filter (Fluval U3) and primer (sand) — I do this routine every week as well, as changing 20% of water, yet today I changed 50% and this did not held much... For preparing tap water for the tank I keep using Prime. Could someone advise me what to do and how rapidly I should come to the action? I have 2 axolotls (6-7 moths) and they don’t look sick, the eat normally and their behavior did not change much, maybe the only issue is that they started to be a little bit more active.
