Was given a 40g bredder aquarium from my son. Some live rock and 2 fish. Fluval 306 filter. No protein skimmer. pH 7.8-8.0 Ammonia 0, Nitrite-0, Nitrates were OFF the charts 160 (+).
Did 10 gal, then 15 gal then 20 gal water change over 3 days. No change in nitrates at all.
LFS recommended NOPOX 30 ml/day. Gave last of 3 doses this morning. Came home 9 hours later to tank so cloudy can't see to back of tank, or see the fish.
Water tested ph 7.8 ammonia 0, nitrites 5, nitrates 10. what the heck happened? Next steps...?
