The use of Colombo Pro Reef salt and the Colombo additives are highly recommended by experts and professionals.

Pro Reef Salt

At least 85% of the ingredients are harvested from natural seawater by environmentally friendly solar evaporation. The fresh salt comes from the coral reefs and therefore contains trace elements in the same ratio as in natural seawater. Because of its origin, Colombo Pro Reef Salt differs substantially from most other salts for reef aquariums. Pro Reef Salt is available in 4KG and 22KG.

Marine Sand

Colombo Marine Sand is entirely natural and is the ideal substrate for marine, reef and African Cichlid freshwater aquaria. Fine marine sand has the ideal size to enable optimum water flow through the substrate for maximum biological activity. The composition of marine sand also makes it a natural and effective buffering media, where a pH of 8.0 to 8.4 is preferred. Rinse well with tap water before usage.
