The pure natural 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.

The formulation for H2Ocean+ salt has been developed by D-D following many months of testing and evaluation. The salt is designed to dissolve quickly and easily and to have a specific chemistry which in our opinion is the optimum formulation to maintain a healthy reef and allow regular water changes whilst maintaining a natural balance.

Its natural origin ensures that the salt contains all 70 main and trace elements in the correct proportions mixed to a homogeneous blend by nature.

when mixed to a S.G: of 1.0268 @ 25°C = 35.5 ppt

RO Water

H2Ocean Pro+ salt is recommended for use with Reverse Osmosis water or soft water with a calcium level lower than 30 mg/l. As the calcium level in H2Ocean+ is already enhanced to 440 mg/l then mixing with hard tap water which contains additional calcium may raise the concentration above normal recommended levels and cause the calcium to precipitate out of solution.

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 Reverse Osmosis units which are available from your retailer. 

Magnesium Pro Plus Formula

Many salts concentrate on boosting calcium levels and ignore magnesium levels.

Maintenance of the correct magnesium concentration is equally important in a reef aquarium and will make it much easier to maintain stable calcium, pH and alkalinity. 

Mixing

The volume of salt water that can be made from a single bucket of salt will depend on the final SG that the salt solution is mixed to.

For a reef aquarium we suggest mixing to an S.G: of 1.0268 @ 25°C = 35.5 ppt by using the salt to water ratio given below.

Using a clean container

• Add 1 Kg of H2Ocean+ to 25 litres of water ( 1 Lb to 3.0 U.S. Gallons )
• Mix well until all of the salt is dissolved and the solution is clear.
• We recommend that you aerate for 24 hours and bring to temperature before use.
• Check the S.G. before addition to the aquarium.
• If required add more salt or water to obtain the correct S.G. reading.
• Remember that S.G. changes with temperature.

D-D recommends the use of a portable refractometer for accurate and consistent measurement of the S.G. of your salt solution.
