Our marine buffer products include the Bio Potassium Blue Treasure Marine Supplement, which can help with buffering elements in your aquarium thanks to its particular blend of ingredients. The potassium in this aquarium buffer provides support with plant growth and plant health, and plays a key role in translocating organic and inorganic compounds. 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.
