ATI Essentials set 3 x 1000ml is an improved Balling method
ATI are the Essentials additions. This is an improved Balling method where virtually nothing else needs to be added to the aquarium.
Administration is best done via a dosing pump.
Bottles of Essentials have also been developed for nano containers up to a maximum of 100 litres.
For nano aquariums, the set of 2 ready-made bottles is sufficient.
For larger aquariums, a set of 3 bottles is supplied that must be dissolved in larger vessels.
