Water chemistry is the whole game in a marine tank, and this is where you will find everything that keeps it in range. The range covers dechlorinators and bacterial starters for a new setup, reef supplements for calcium, alkalinity, magnesium and trace elements, salt mixes, RO/DI filtration and the test kits you check it all with. Brands include Red Sea, Seachem, API, Aqua Medic, AquaVitro, Continuum and Reef Pure RO.
RO/DI stands for reverse osmosis deionisation, a two stage filter that strips tap water back to pure water, so you are not adding phosphate, nitrate or copper to the tank with every top up.
Browse Additives & Supplements, Test Kits, Aquarium Salt and RO/DI Water Filtration, or read the parameter guides in our Education Centre.
