Warner Marine C-MAX is a 2-Part Calcium and Alkalinity Supplement that adds both Calcium and Carbonate Alkalinity with major and minor elements by adding equal amounts of Part A and B.

C-MAX will maintain Calcium and buffer levels and end Calcium/Alkalinity instability.

Crucially, C-MAX will not disrupt ionic balance and will replenish salts lost due to protein skimming. Some aquariums may experience a slight increase in salinity which can be easily corrected by removing a small amount of aquarium water and replacing with purified fresh water.

Warner Marine C-MAX Part A is the Calcium based component of the C-MAX 2 Part system. C-MAX Part A should be used with C-MAX Part B for a balanced Calcium/Alkalinity supplement. In addition, C-MAX Part A may be used alone to boost Calcium levels to correct a Calcium/Alkalinity imbalance before using both parts simultaneously.




Dose equal amounts of C-MAX Parts A and B separately into an area of strong water movement or the sump area. Rinse measuring cup between use of Parts A and B. Add 5ml (1 teaspoon) of Parts A and B separately per 25 gallons of aquarium water three times per week. Calcium should be maintained between 400-450ppm. Adjust dosage of Parts A and B respectively to maintain this parameter.

Contains: Ultra-Pure 5-Stage Reverse Osmosis/Deionized water, Calcium Chloride and an ionically balanced blend of inorganic salts.
