D+D Aquarium Solutions Sea Water Refractometer

D+D Aquarium Solutions Sea Water Refractometer

£33.99

A refractometer is a simple and robust way of accurately measuring the salinity within your aquarium and should be used by every serious marine aquarist.

The refractometer works on the principle of refraction of light to determine the salinity and is very accurate but also very simple and robust, unlike good quality glass hydrometers which are easily broken.

Light enters the instrument at one end and passes through a sample of the aquarium water which causes it to be refracted, (bends the light), depending on the salinity of the water. The refracted light is reflected off a scale inside and can be viewed through an eyepiece on the opposite end of the instrument.

What’s different between our NEW refractometer and others you might ask?

Almost all, if not all, of the refractometers currently available to the aquarium hobby are designed for measuring saltwater (sodium chloride or brine solution) and not true ‘seawater’. Although seawater is mostly sodium chloride it also contains other elements such as magnesium and calcium that change the refractive index slightly and will give a slightly different result.

The most common symptom of this difference in refractive index can be seen when mixing up salt as per salt manufacturer’s instructions and achieving a solution strength where it appears, through testing, that the levels of elements are lower than stated by the manufacturer. In actual fact all of the levels are low as the salinity is not as high as the aquarist believes – we have all seen low Ca or Mg for a given SG with almost all brands of salt.

It turns out that a 35ppt solution of true seawater has the same refractive index as a 36.5ppt solution of brine and so when using a brine/salt refractometer the salinity is likely to be low by 1.5ppt. This can be allowed for by the aquarist but only if they are aware of the difference.

After extensive development, D-D’s new refractometer addresses this issue, giving true salinity results when correctly calibrated and greater accuracy than previously attainable.

Rowacarbon

Rowacarbon

Quantity:


Size


High performance activated carbon for crystal clear water in freshwater and saltwater aquariums.
Rowacarbon is an unusually high-performance activated carbon based on the finest quality hard coal and contains extremely low levels of phosphate.

Within the aquarium activated carbon will remove toxins and yellowing from the water which will improve the health of your livestock and improve the penetration of light leaving your aquarium crystal clear.

Many low cost carbon products on the market place are washed in phosphoric acid as a final stage of their preparation and can release high levels of phosphate into the water. Rowacarbon contains extremely low levels of phosphate.

Problems with algae are often caused by the release of phosphate from activated carbon with high POI (Phosphate Output Index) levels - often as high as 14.0, which inhibits lime synthesis in coralline algae, corals and other organisms that deposit lime.

Rowacarbon is distinguished by its exceptionally low POI level of only 1.3 which is considerably below detection levels of phosphate test kits available to the hobbyist.

Rowaphos

Rowaphos is the professional method of removing phosphate and silicate in all types of aquariums and ponds.

In freshwater or salt water aquariums, phosphates will feed nuisance algae which can overrun plants and expensive corals, spoiling the aesthetics of the tank and in extreme cases killing its inhabitants.

Within the reef aquarium, phosphates will greatly affect the formation of coral skeletons by reducing calcification by over 50% and by inhibiting the deposition of strontium. It is suggested by Borneman that phosphates are a direct poison to calcification.

Rowaphos is a unique and patented, man made ferric hydroxide material chemically engineered for the efficient removal of phosphates, arsenic and silicates from fresh and salt water, having initially been developed in Germany for treating mains water supplies.

Rowaphos should not be confused with natural materials, which are generally based on aluminium oxide, (zeolite) or even other iron based products which claim to be the same product from other manufacturers.
