White/grayish cloud

[Ozone]

I treat one of my tank with Ich medication two week ago since then I’m having problem in my tank with water cloudiness(white/grayish cloud) I’m doing 50% water change it helps for one day after 24h same thing again!!!
Is it bacteria blooms? Did ich medication kill all beneficial bacteria’s?
What can I do to deal with it??

Any help really appreciated :rolleyes:

Ich medicationworks against against "good" ciliates as well as the bad one, Ichthyophthirius. Effective treatments against Ich also decimate the population of other single-celled organisms in the plankton.

Your bloom is temporary. You could speed up the clearing with a gallon of water and mulm siphoned from a healthy clear balanced aquarium. A "founder population" that would include some elements now missing in your plankton. But as populations in the plankton right themselves, once the windfall of dead plankton is consumed, the water will clear on its own.
