CO2 DI Resin Depletion Calculator

* Special thanks to Boomer from www.reefcentral.com for his help.

This calculator measures how much of a DI resin is being depleted by CO2 alone. All four input parameters should be measured on the water entering the DI resin (usually the water leaving the RO filter).

Alkalinity:
 

pH:
 pH Units

Temperature:
 

Total Dissolved Solids (TDS):
 Parts-Per-Million





Depletion by CO2:
 %

This calculator assumes that the DI filter is successfully producing water with zero total dissolved solids (TDS).
