The turbidity of water in aquariums and ponds can be due to various causes, the most frequent of all is the left over feeding. Food that is not eaten by fish falls to the bottom and is gradually broken down by bacteria, fungi and other microorganisms present in the water, which reproduce rapidly and are so small that box or bottom filters cannot retain them.
Turbidel acts on all these tiny particles by flocculating them; that is, it manages to join several of them with the purpose of forming increasingly larger particles so that ordinary filters are able to retain them. Turbidel also works just as effectively when the turbidity of the water is caused by very fine mineral particles from the sand or gravel at the bottom of the aquarium
Turbidel works based on the electrostatic forces present in the suspended particles, so it is NOT oxidizing, it has no color, it DOES NOT modify the quality of the water, it is NOT toxic and it DOES NOT alter the pH value.
