BALLING METHODThe study of the chemical reactions that hard corals use to form their skeleton led H. W. Balling to invent a method (which takes its name) to supplement the consumption of the basic elements. Enter Calcium, Magnesium and Hydrogen carbonate in the aquarium in calculated proportions without going to alter the ionic balance of the sea water. The E'quo, has improved and facilitated the management of the method by formulating a new more balanced version, enriching it with Macros and Microelements, the latter often difficult to evaluate. The E'quo method, consists of 4 complementary aqueous solutions: DOSO REEF 1,2,3,4. These solutions are ready to be used with dosometric / peristaltic pumps.
