JOR Water Conditioner Calcium Rocks for Baby Shrimps, Isopods, and Crayfish, Enhances Pet Color, Provides Hideout, Breeding Spot, Beneficial for Shedding, Rustic Decor for Big and Nano Tanks, 3.5 oz.

I bought this product for my shrimp tank. They love to graze on it, and it keeps them healthy.

My Mystery snails just LOVE these rocks!!!I did rinse them off with distilled then springwater first before placing in aquarium. The snails go for them immediately!!!

Using one a month for my tank and my plants are going nuts. Shrimp like holding on and seem healthy.Super happy

Love this product not only do they help with hard water balance.They also give my fish and snails vitamins and minerals they need to grow fast and have beautiful color.

Thought I was doing a good thing for my shrimp and snails, and the white rocks looked so nice against the dark substrate in the tank. I rinsed the dust (so much dust!), soaked the rocks, and rinsed again before adding them to my 42 gal tank. My water parameters were way off 3 days later. My shrimp died before I caught it and my fish were lethargic and flashing. Took all but the tiniest of the rocks out, half water change, pulled every trick I know to balance water parameters quickly and got things back to normal. DO NOT ADD THE WHOLE BAG TO YOUR TANK. It's a tiny little bag, but the high mineral content will mess things up. Now I'm afraid to put any more of these rocks in my tank!
