Stock up your tanks with the calcium, which your corals, calcareous algae, and clams need with the Two Little Fishies Kalkwassar from Pet Store. This saturated Calcium Hydroxide, also known as Kalkwasser, maintains the alkalinity of the aquarium water and provides the calcium that calcifying organisms in your tank feed on to strengthen their shells, crusts and skeletons.

This solution also helps maintain the pH level and phosphate precipitate of your aquarium. It facilitates protein skimming when it reacts with organic matters and fatty acids. The solution creates a clean, clear and healthy environment for your aquatic inhabitants.

The Two Little Fishies Kalkwassar works best with the CombiSan, which replenishes iron, strontium, iodine molybdenum, trace and micronutrients that your inhabitants need as well. Proven for its safety and effectiveness, this kalkwasser should not be mixed with the CombiSan supplement in dosing reservoir. It is designed for aquarium use and should not be used in potable water or for human consumption. So be sure to keep it out of reach of children. This should not be used on aquaculture tanks raising fish for human consumption. The Kalkwassar comes in a four-pound bucket for your easy use. Mix enough doses for every gallon of aquarium water and you get a better tank for your pets.
