The best place to get crushed oyster shells is at a store that sells
feed for ducks or chickens. Like Southern States or another farm supply
store. You can get like a 50 lb. bag of crushed
oyster shells for about $7 or so. I've raised ducks, and crushed oyster
shells are mixed in with their food to give them calcium.
Another source is a pet store. They will sell a small
box of crushed oyster shells for grit for pet birds.
You can put the oyster shells in a mesh bag and put them in your
filter. It will increase the hardness of your water. When the water is
at the desired hardness, take it out. I assume it's the calcium from
the oyster shells that increases the hardness.
