Premium Grade Mineral Filter, pH Adjusting, Re-mineralizer
CRL-Min Mineral Filter Cartridge contains a premium grade mineral media for the re-mineralization of acidic or low pH water such as produced by Reverse Osmosis (RO) Systems. CRL-Min dissolves when the pH drops, produces calcium and boosts alkalinity -and it's got a number of distinct advantages over Limestone or Calcite.
With Limestone or Calcite, much of their "power" is locked away and may not be seen until the pH drops below 7.0 but CRL-Min kicks in when the pH drops below 8.2, so it keeps the pH higher and adds more minerals to the water.
Applications include post mineral filter for Reverse Osmosis (RO), Distillation, and Ultra High Purity Water Dispensing equipment. It an ideal mineral filter cartridge for marine fish tanks, and also for some freshwater fishes to increase the pH of the water.
It contains no silica (which encourages the growth of algae), but contains small quantities of useful trace elements like magnesium and strontium.
Espresso machine manufacturers recommend this 10" CRL-Min mineral filter cartridge for those of you who are using an Reverse Osmosis (RO) system to remove hardness from your water. This filter will add back minerals in trace amounts to your water to prevent leaching of your copper boiler over time.

A simple way to raise the pH of Reverse Osmosis (RO) Permeate to make it non-aggressive and compatible with copper piping is to use a CRL-Min post mineral filter. One of the advantages of CRL-Min is its self-limiting property. It corrects pH only excessive enough to reach a non-corrosive equilibrium and does not cause any scum formation.
How Do CRL-Min postfilters Work?
Install into a standard 10" filter housing after the RO System. The CRL-Min media slowly dissolves, releasing the right amount of mineral to make the water non-corrosive.
