These shells are great for adding hardness into your water and work as dechlorinator as well! Often times we need more minerals for our snails, shrimp, plants, goldfish and african cichlids tanks. What size you need depends on your aquarium. We recommend testing your water and adjusting based on water change schedule. 

Here are some very loose guidelines:
3 Pak - 1 shell per month for 5 to 10 gallon aquariums.

2/5 Ounce - 1 shell per month for 20-30 gallon aquariums.

1 1/3 Ounce - 1 shell per month for 40 to 55 gallon aquariums.

2 1/4 Ounce - 1 shell per month for 75 and larger aquariums.

Work fast

I put these into my tanks and they dissolved rapidly over the course of a couple days. Snails seem happier. So do the guppies.

Great product!

I use these in all of my tanks. Snails are always crusin' over them! Which tells me, there is something in them they want.

Great stuff

I use them in a nano tank with a few tetras, snail and Amano shrimp. Really helps since I have soft water.
