Product Information

The H2Ocean pro formula marine salts have a strong reputation for quality and consistent parameters, which have been producing fantastic results for reef hobbyists around the world for many years. There are now 2 versions of this popular reef salt and both formulations are manufactured by a solar evaporative process, which creates a totally natural base salt where all of the main and trace elements are in complete balance as nature intended. You can purchase the original H2Ocean Pro+ Salt here.

H2Ocean Dosing Formula Marine Salt is then specially enhanced for aquarium use by elevating specific elements that over time become depleted, such as calcium and magnesium which are used by corals and coralline algae for growth. With H2Ocean reef salt the calcium and alkalinity are in the correct ratios keeping the ionic balance in equilibrium with natural levels which is so important for healthy coral growth.

Use of this specific formulation allows interim water changes to be made to your aquarium without observing temporary elevations in the dKH or calcium and is therefore ideal for dosing.

Both H2Ocean reef salt formulations have an extremely low hydration level compared to many other salts. This is achieved through production under strictly controlled conditions to prevent water from the atmosphere from being absorbed into the salt so that it is now 3% stronger, therefore kilo for kilo you get more salt and less water in your pack.

Mixing and Salinity Measurement

The volume of salt water that can be made from a single bucket of salt will depend on the final salinity that the salt solution is mixed to. See side of bucket for details. For a reef aquarium D&D suggest mixing to a salinity of 35.0 ppt and recommend the use of the D&D Refractometer for accurate and consistent measurement of the salinity of your salt solution.

The salt should be added to the aquarium when clear and after 30 minutes of mixing. Extended mixing times can allow the solution to react with CO2 in the atmosphere and can result in a slight precipitation of calcium carbonate.

23kg bucket for 592-702ltrs.

Use of RO Water

H2Ocean Pro salt is recommended for use with Reverse Osmosis water or soft water with a calcium level below 30 mg/l.

RO water removes undesirable ions like phosphate and nitrate from your tap water which otherwise would contribute to nuisance algae in your aquarium. D&D manufactures a range of RO units suitable for every tank size.
