Crushed Coral brands?

[Bettalover29]

What is the best crushed coral to use to raise my KH? I would like some advice to make sure I don't buy a bad brand.

In theory, they should all be identical—skeletons from hard coral will be the same regardless of who you're buying it from. There's no "Cadillac" option when it comes to ocean bones. Regardless of the seller, just make sure you rinse it will before use.

I use chicken grit that I buy on amazon. its 5 dollars for 5 pounds, its basically crushed oyster shells and Coral, and it works really well. for crushed coral, I dont really know. some people say if you get Florida crushed coral, it will buffer the water a lot more than coral from somewhere else, but I wouldn't think about it too much.
