5 lbs Calcite Corosex Media – Small Bag pH Neutralizer

This 5 lbs bag of Calcite and Corosex mix is a natural mineral media used to fix acidic water. It is made of approximately 95% calcium carbonate and 3% magnesium carbonate. This size is ideal for small maintenance jobs or topping off your neutralizer tank.

When acidic water touches the media, the mineral rock slowly dissolves. This raises the pH and helps stop lead, copper, and other metals from leaching out of your plumbing. It is a slow-reacting and low-cost way to balance your water.
