Fritz PRO Bulk Sodium Carbonate Professional Aquarium Supplement.
Fritz ProAquatics Sodium Carbonate can be used alone or as part of a two part calcium & alkalinity supplement system to raise alkalinity in enclosed reef systems. Monitoring and maintaining alkalinity is an important part of helping to stabilize water chemistry values, resulting in better coral, coralline algae and invertebrate growth and health.
Add one teaspoon (5 g) per 65 gallons to raise alkalinity by approximately 1 dKH. Dissolve appropriate amount in RO / DI water, slowly add to a high flow area, ideally into a sump. Monitor pH while dosing. Avoid immediate impact of pH change to more than +/- 0.2. Re-test and repeat dose until desired level is reached.
NOTE: Due to the variation of granular size, conversion between volume and weight of powdered products are approximate; as a precaution, dose less than the calculated amount and measure the effect before adding the total amount.
