Q. Is calcium carbonate suitable for supplementing dogs in a home-prepared diet?

Q. Can this carbonate can be mixed with raw mince for wild magpies?

A. Assuming calcium carbonate is suitable for magpies then our food-grade version would also be fine. The food-grade version is just a more pure type of calcium carbonate. From my reading, online calcium carbonate seems fine for magpies.

A. We asked a customer of ours with experience with ferrets and he suggested about 4 grams per kg

Q. How much calcium carbonate should I add to the meat im feeding Kookaburras and Magpies?

A. I found this information on the RSPCA Victoria website " In the wild these birds eat insects and small animals (vertebrates). It is important that two heaped teaspoons of calcium carbonate per kg of meat mince are added to meals to prevent bone problems. Soaked complete dry dog food, hard-boiled egg and cheese can be added. Earthworms, grubs, and other insects can also be fed" (14/10/21)

Q. Is your calcium carbonate suitable as a buffer to the water hardness in ponds?

A. We got this feedback from a customer "Received the calcium carbonate and I used it for a newly established freshwater pond (400L).

Dosage was roughly around two teaspoons per 50 litres of water and the calcium carbonate has increased the KH and GH levels which should help stabilise the PH levels (as advised by a local water lily expert). 

The water levels are spot on and a test that I did a few hours after adding the calcium carbonate has come back perfect for my Goldfish and water lilies. 

6-7 days after being added, the water PH readings are still great! No drops or increases so it's very stable. 

It does make the water cloudy when first added like all other calcium carbonates that I’ve used, but after dissolving and some settling the water is very clear even with the heat, humidity and sun that the water is exposed to here in my area. Overall, cannot think of a negative thing to say about the Calcium carbonate"
