The Revolutionary 8.3x Seawater Concentrate
ATI® Absolute Ocean is a revolutionary liquid seawater concentrate designed for maximum precision, purity, and ease of use. This 8.3x concentrated solution is the perfect alternative to traditional synthetic salt mixes, especially for nano-reefs or systems where storage and mixing speed are priorities. Simply combine with RODI water for immediate, laboratory-grade saltwater that is virtually identical to natural seawater.
The Absolute Ocean Advantage
-
True Natural Chemistry: High-precision ICP laboratory measurements ensure that all major and trace elements are perfectly adjusted. Even trace elements in the parts-per-billion (ppb) range, such as vanadium, are tuned to near-natural levels.
-
Maximum Purity: Formulated using only pharmaceutically and analytically pure salts, ensuring a final solution free from the impurities often found in mined salt products.
-
Perfect Homogeneity: Because it is a liquid, Absolute Ocean eliminates the "layering" or separation of elements that can occur in dry salt buckets. Every drop is identical to the last.
-
Ready for Immediate Use: There is no "mixing time" required. Once diluted with RODI water, the solution is immediately clear and ready to be added to your aquarium.
-
ICP Quality Control: Every batch is continuously monitored by the ATI® Lab. Users can access the specific analysis of their batch via the QR code on the packaging.
