Pure biology!
The most important thing in a functioning saltwater aquarium, but still totally underestimated by most aquarists, is the bacterial fauna. Our ZEO bak contains many bacterial strains, some of which form bacterioplankton in combination with ZEO food. This is absorbed by many corals.
Dosage: 1 drop per 100L once or twice a week. It is dosed directly into the aquarium.
Shelf life 3 years.
