Our AquaForest Kh Buffer is another great option - this marine pH buffer is designed to maintain a constant carbonate hardness level throughout your reef aquarium.
You’ll find a wide range of Aquaforest marine supplements in our collection, including Reef Mineral Salt to help prevent mineral deficiency in your reef aquarium, as well as Calcium to allow you to top up the calcium levels in your tank. The levels of calcium in seawater play an important role in helping coral develop properly, with a calcium marine supplement allowing you to mimic these conditions in your reef aquarium.
Reef Probiotics are another of the marine supplements you’ll find in our collection. These are important reef aquarium supplements, as they contain specific probiotic bacterial strains that are designed to speed up the decomposition of organic matter in your tank. This is essential for maintaining optimal conditions in your aquarium. Buy Reef Probiotic marine supplements in different quantities, depending on how much you get through.

Aquaforest Components A-B-C-K Strong Set (4 x 75ml)£26.45
Components Strong contains concentrated trace elements intended for use in reef aquariums. Components Strong in combination with Calcium, Magnesium, KH Buffer and Reef Mineral Salt are a complete set designed to maintain a reef aquarium by the method proposed by H. W. Balling, therefore these products should be used in parallel. Due to the fact that the microelements in the aquarium are consumed in the right proportion with the macroelements, the concentrations of Components Strong have been developed based on other values. Only the use of the entire range of Aquaforest products ensures effectiveness and guarantees the chemical balance in the aquarium. The amount of microelements fed depends on the individual needs of the aquarium for magnesium and calcium.
