Livestock arrives in and out of stock very regularly, depending upon availability of the item from the source. The more rare and expensive items are often difficult to hold in stock, and can take time to source, so we generally require a deposit to locate and purchase the extremely rare items

Kalkwasser - Translates from the German word for limewater and is a solution made by dissolving Calcium Hydroxide in water. The resultant fresh solution is alkaline with a pH of 12.4 and contains a ready supply of both Calcium ions and Carbonate ions. The solution reacts readily with CO2 in the atmosphere to form calcium carbonate and so it must be made in a relatively airtight environment which is where the Kalkwasser Stirrer comes in to play.

R.O water is pumped through a bed of unreacted calcium hydroxide in the bottom of the reactor which is dissolved by the stirring action until the solution becomes concentrated preventing further dissolving. The clear Kalkwasser solution decants by gravity off the top of the reactor and into the sump or tank.
