ClackA8011 Corosex Brownish White Aggressive pH Correction Media for Acidic Water, 0.66 CF Bag

The item was what I expected. It was well packaged. Attached are the images of the 50 pound bag that I received.

Use sparingly. It works very well. You can over-soften your water very easily.

Makes 80/20 mix

Product arrived quickly but the bag was broken and the product was contaminated and unusable.

mixes well with the calcite for an 80/20 mix.
