Ready-to-use seawater for reef aquariums
The SEA10 pack contains two 10L cans (SEA10-1 and SEA10-2) and two 1L bottles (SEA10-3) to complete the preparation. Simply mix them in the indicated proportions with reverse osmosis water to obtain seawater perfectly suited to reefs. The ease of use avoids dosage errors often associated with salts in powder form or in conventional buckets.
10x Concentrate: a sustainable, economical and smart choice
SEA10 is approximately ten times more concentrated than traditional seawater mixes. Less volume to transport, less storage, less plastic. All with a significantly reduced environmental impact . It's a particularly popular solution for aquarists looking for a clean, fast, and easy-to-integrate system into their maintenance routine.
Laboratory quality: maximum purity guaranteed
SEA10 solutions are made from analytically pure salts , controlled in Fauna Marin 's ICP LAB . Each batch is tested to ensure consistent and reliable values. The result: ultra-stable seawater from the first filling, which respects the ionic balance necessary for the health of the most sensitive corals, fish and invertebrates.
