So it doesn't have "Calcium Carbonate and Silica Quartz" listed?
Just bag them and toss them in the waterfall or filter without washing, like I did with the oyster shells? Or should I find the real oyster shells?Calcium Carbonate will help buffer the pH. The Silica Quartz is a non-reactive binder.
What you purchased is not truly crushed oyster shells but a product manufactured to produce the identical results.

Thanks so muchWhat you have will provide the same results as oyster shells. I would rinse before placing in skimmer or filter
