Are there any additives or impurities in Zelbrite?
No, Zelbrite is manufactured entirely from a naturally occurring zeolitic mineral resource. The manufacturing process does not involve treatment with, or addition, of any form of chemicals or other materials. Note: Direct Pool Supplies does not ship sand or Zelbrite due to the weight & high freight costs. We only sell it out of our shop for local pick up. Our customers can usually source the product locally.
