Severely Cloudy tank/ sudden nitrite&nitrate change after NOPOX

[Proax9]

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...?

Why haven’t you read the instructions? That dose is way to high for Your tank size. I would recommend move all the fish to a quarantine system and increase water flow asap.

Cloudiness is a bacterial bloom. You overdosed your tank.

I questioned the dosage I was told in the store- the owner of the lfs said- 'listen to me- you need 30 ml daily". Guess I learned a hard lesson who not to listen to.

BACTERIAL WHICH MAY HAVE BEEN TRIGGERED BY NOPOX (oops on the caps). When a sudden increase in the number of bacterial colonies is generated and becomes suspended in the water and in turn grows so quickly that it becomes more visible causing the water to become milky and hazy in appearance due to a nutrient increase in the water especially nitrates and phosphates, so check those two.



What some dont know, in a newer tank, use of NoPox can triggers blooms but mainly . . . . . When there is a sudden increase in the number of bacterial colonies that builds and becomes suspended in the water and grows at a fast rate, it becomes more visible causing the water to become milky and hazy in appearance due to an increase in nutrients especially with nitrates and phosphates, so check those two. Can also be poor filtration, not movement, overfeeding and even your water source especially if RODI filters are nearing end of useful life.
If the bacteria does not get enough oxygen, this issue begins

Way too much. Just for reference, I dose 6 mL NOPOX daily in my 45g, all while staying on top of NO3 and PO4 to make sure nothing bottoms out, and also to see the progression.

You need to run a skimmer when you carbon dose, which you are not doing. Where is the bacteria to go?
