Detailed product description

Detailed description:

Mr. Bacteria No. 11 is a mixture of bacterial spores, enzymes, and nutrients necessary for the activity of microorganisms. The result of the action of the product in aquariums is the decomposition of organic sediments on the bottom and in water column of the aquarium using highly mobile natural unmodified aerobic bacteria and facultative anaerobic bacteria with positive chemotaxis (they can recognize the type of chemical waste in the aquarium and swim to it). At the same time, the water column is significantly cleaned. Simultaneously, the dissolved oxygen content increases. With regular use of Mr. Bacteria No. 11 guarantees a high reproduction of bacteria, which results in continuous cleaning of the aquarium.

Bacterial force:

The higher the content of bacteria in the product, the higher its bacterial strength. That is why we maximize the number of bacteria in each of our products, thus increasing its effectiveness!

We declare that our products contain an extra number of bacteria, which help to eliminate the odour and organic waste very effectively!
