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.
In nature there is a natural balance between the calcium, alkalinity and magnesium levels. Many salts are found to be either unnaturally high in calcium or high in alkalinity and therefore with these salts either extra buffer or extra calcium is required to be added to return the natural balance.
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.
The formulation for H2Ocean salt has been continually developed by D-D over many years. 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.
Calcium and magnesium levels are designed to replace those that are used up through coral growth within the aquarium, whereas chloride levels are slightly lowered to
allow post additions of calcium and magnesium chloride with a minimized effect on the chloride balance.
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.
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 & 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 we suggest mixing to a salinity of 35.0 ppt and recommend the use of the D-D Portable SEAWATER 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.
Typical Water Volumes / Pack
23Kg Bucket for 592-702 lts (50.7 lbs for 156-185 US Gallons)
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.
