## Questions & Answers

**Q: Can this be used in freshwater aquariums to give mystery snails calcium?**
A: yes- I add some to my mystery snail tank- I've got about 6 in a 5 gallon tank.  I add it according to the prescribed dosage on the bottle with the hope that it will strengthen the shell.

**Q: Can i do this in a 3 gallon tank**
A: yes- the recommended dose is 5 ml/10 gal  (not positive- but in directions on bottle) so for a 3 gal tank you'd add 1.5 ml.  bottle has measurements on cap  i have a snail 3 gall tank with about 7 small nerite snails.  i always add some when doing a water change.  good luck!  Perry A.

**Q: Would this work for my Red Eared Slider tank?**
A: Yes, If you are looking to increase your calcium level or general hardness in your aquarium water this product will work.  To dose the aquarium use API General Hardness test kit or API Calcium Test kit to reach your desired level.

**Q: Can I use this product with a betta fish and a mystery snail in a freshwater tank?**
A: This is not harmful to fish. It does give necessary calcium for the snail. Make sure you are adding proper amounts according to container. This is what I use in my fresh water tanks for snails and shrimp.
