We noticed these containers of Calcium Pronto, Magnesium Pronto, and KH Power at Two Little Fishies’ InterZoo booth. They represent a line of dry additives and will offer hobbyists an economical option of making their own stock solutions.
Magnesium Pronto is a mix of anhydrous magnesium chloride and magnesium sulfate, while Calcium Pronto is made up of a fast dissolving calcium chloride. KH Power takes care of building alkalinity and stabilizing pH via a blend of carbonates, bicarbonates and borate salts.
Once a pH of 8.3 is reached, further additions will only raise KH. If you are someone who prefers to make your own stock solutions of reef-building additives, definitely give these new offerings from two Little Fishies a try.
