Product Description
Calcium Rocks by JOR also acts as a water conditioner that maintains the ideal environment for your aquatic pets. It takes away sludge coming from the tank while not causing adverse effects on your pets.
Each pack weighs 2 oz. of stones, and when placed inside the tank, they slowly release calcium while dissolving. Turtles can ingest all the beneficial elements that will come out from our rocks to help their proper shell growth and development.
You can dissolve these calcium stones in water or put them in a feeding bowl for your pets to eat. In a breeding environment, add them directly or crush them and mix them in food. They can also nibble them directly, and it’s perfectly fine. You can also utilize these rocks for other crustaceans and aquatic animals, and they will enjoy the same benefits of keeping their vibrancy, durable shells, and longer lives.

Works great
I use them in cherry shrimp tank to buffer the water and keep my kh from plummeting. I leave them in front of tank so I can see when they start dissolving in my very hard water.

Lots of calcium!
Got these to harden aquarium water, and the shrimp in the tank immediately jumped on them. Nice and chalky, with a variety of chunk sizes

Great calcium source for aquariums
I ordered these for my aquarium when I noticed my snails struggling – their shells were weakening and they seemed to be much less active than normal. An adequate replacement for cuttlefish bone (and much smaller), these calcium rocks serve the same purpose and have really improved quality of life for both my snails and shrimp. Reasonably priced for the amount received – enough calcium for my ten gallon tall tank with leftovers for replacement in a few months. Highly recommend for any tanks housing shelled animals.
