D-D True Seawater Refractometer
$55.30$79.00Add to cartEasier to Read & ATC
Easier to Read
One of the other problems with most refractometers is that the scale displayed normally reads from 0-100ppt when we are really only interested in the region from 30-40ppt. Our new Seawater Refractometer has therefore been specifically designed to read from 0-40ppt which gives you 2.5 times the resolution of a normal 0-100 scale.
Auto Temperature Compensation (ATC)
There is a lot of misunderstanding concerning the way the ATC feature works and its effect on the refractometer at different ambient room temperatures.
Salinity is a measurement of a mass of salt in a mass of water and therefore does not vary with temperature however a refractometer does not measure salinity directly but measures the refractive index which is then displayed as salinity. The refractive index of a solution does vary with temperature therefore the reading that you measure with a refractometer is always temperature dependant.
An ATC refractometer has a bimetal strip inside the instrument that moves the reading scale as the temperature changes to compensate for the change in refractive index. What people do not generally understand is that it is the temperature of the instrument and not the water temperature that is important as the small sample of water used for testing will equilibrate within seconds to the temperature of the refractometer.
Once correctly calibrated at the set calibration temperature of 20oC the refractometer can then be used in environments where the ambient temperature and therefore instrument temperature would heat up or cool down within the range of the ATC which is between 10 and 30 centigrade.
Calibration
If you look at the scale above you will see that the refractometer states that it is calibrated at and displays the SG of seawater at 20C.
Most salt refractometers use this temperature and will be marked 20C or 20/20. Calibration should always be carried out with the instrument at 20C which is close to the average room temperature in most cases. Allow the refractometer to stand at this temperature for 30 minutes to equilibrate.
The D-D refractometer is designed with a copper body which is more expensive to manufacture but responds faster to ambient temperature changes than other materials.
Note that the refractive index is also dependant on the wavelength of light too and therefore a light source closest to daylight should also be used.
D-D refractometers are calibrated at 20C and so the calculated specific gravity at 35ppt displays a reading of 1.0266. This is the equivalent to a specific gravity reading of 1.0264 for a water sample temperature of 25C using a standard hydrometer that has a calibration temperature of 77F or 25C.

DD H2Ocean pro+ Aquarium Salt 23kg ( 575-690 liters )
$87.50$125.00Add to cartH2Ocean Pro+ is a new pro formula aquarium salt – produced by a solar evaporative process which produces a totally natural base salt where all of the main and trace elements are in complete balance as nature intended.
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.
Free from Nitrate and Phosphate.
CHEMISTRY
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.Calcium and Magnesium levels are boosted to replace that 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 affect on the chloride balance.
Parameters when mixed to a S.G: of 1.025 @ 25°C = 35.5 ppt
Parameters Level Range Units pH 8.3 8.2-8.4 dKH 9.3 8.7-9.8 Calcium (Ca2+) 440 430-460 mg/l Magnesium (Mg2+) 1340 1300-1380 mg/l Chloride (Cl-) 19550 19960-20130 mg/l Potassium (K+) 410 380-420 mg/l 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
Using a clean container:- Add 1 Kg of H2Ocean+ to 24.2 litres of water ( 1 Lb to 2.9 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.
