Calgrit is a natural mineral grit derived from calcium carbonate, which is a great alternative to shell grit, providing more calcium (for hard egg shells) and more essential minerals than regular grit. Calgrit is ideal for laying chickens to help them cope with egg shell production & to aid in bird digestion. Also suitable for other birds & for freshwater turtles as a tank additive.

Calgrit for fresh water turtles:

Calgrit is a granular shaped limestone that adds Calcium and raises Carbonate Hardness (KH) in your water to help keep your PH in the 7.5 - 8.0 range. 2 kg calgrit will do a 2 foot (50 litre) tank. There is no need to rinse this product before putting it into your tank. Your tank will go cloudy for 24-48 hours, and your turtles are fine to be in the water during this time.

Disclaimer: Only the 20 kg size is sent in its original packaging. The other sizes are repackaged and provided in clear plastic bags. If multiple 5kg bags are purchased, they may be combined into one bag.
