I don't even know if I would recommend it to anyone... waste of money!!!!!! The brand disappointed me!!!!! Water measurements were fine, with the appropriate dosage using a dosimeter in a 150-liter aquarium, and the cloudiness remains after 3 days!!!!!! Not crystal clear water, but I have the impression that it made it worse!!!!!!

Very good and powerful!
It clouds the water a little like a smoke bomb, but that means it does the job.
In a 200-liter aquarium, it made it crystal clear in 4 hours.
Preferably, clean the filters after 48 hours because they will quickly become saturated with dirt.

Very powerful product. In 4 hours it cleared up any cloudiness that was present. At first, it looks like smoke in the water and it becomes even cloudier. It has a strong reaction once it is dropped into the water.
