Powdered alkalinity buffer. Raises and stabilizes KH and pH. Safe for all reef inhabitants. Can be used daily or as needed. Dissolves quickly and completely.

Live saltwater nitrifying bacteria. Contains both Nitrosomonas and Nitrobacter strains. Instantly cycles new aquariums. Reduces ammonia and nitrite. Safe to overdose.

High-concentration bacteria for marine aquariums. 10x more concentrated than FritzZyme 9. Instantly establishes biological filtration. Ideal for new tanks or after medication.

Coral feeding suspension. Contains amino acids, vitamins, and natural plankton. Promotes polyp extension and feeding response. Suitable for all coral types including SPS and LPS.

Complete marine salt for reef aquariums. Balanced formula with enhanced calcium and alkalinity. Dissolves quickly and completely.

Part 2 of Fritz RPM 2-part system. Buffered alkalinity solution with optimal carbonate/bicarbonate blend. Maintains stable pH and KH. Works in perfect balance with RPM Calcium.

Part 1 of Fritz RPM 2-part system. High-purity calcium chloride solution. Rapidly absorbed by corals for skeletal growth. Pharmaceutical grade ingredients ensure no impurities.

Liquid carbon source for bacterial nutrient export. Feeds beneficial bacteria to reduce nitrates and phosphates. Promotes natural biological filtration. Compatible with all reef systems.

Concentrated iodide supplement. Essential for soft corals, crustacean molting, and macroalgae. Enhances coral metabolism and coloration. Use based on testing.

Magnesium supplement with balanced sulfate/chloride ratio. Prevents calcium/alkalinity precipitation. Essential for proper ionic balance in reef aquariums.

Granular ferric oxide phosphate remover. High capacity phosphate absorption. Safe for all marine life. Does not leach phosphates back. For use in media reactors or filter bags.

High alkalinity salt mix for SPS-dominant systems. Elevated alkalinity and calcium for demanding coral growth.
