<b> Calcium</b> Calcium
Calcium is a major constituent of calcareous algae, skeletal material of hard corals and the skeletal needles of soft/leather corals. Calcium also fulfills many biological functions.
Quite often a too low calcium concentration retards coral and calcareous algae growth.

 <b>KH/Alk</b> KH/Alk
Calcium alone cannot form the skeletal material of corals and allow calcareous algae to grow. Some other substances are needed as well. A few other constituents are carbonate and bicarbonate. These two substances also have a major impact on the stabilization of the pH in the proper range of 8.1 – 8.4. Such stabilization is also called buffering.
The total carbonate and bicarbonate concentration is also called carbonate alkalinity or carbonate hardness. The only difference between alkalinity and carbonate hardness is a conversion factor.

<b>Magnesium</b> Magnesium
Magnesium is present in NSW in a fairly high concentration (1300 - 1400 mg/L). Magnesium is an essential part of chlorophyll, which is necessary for photosynthesis. Without photosynthesis plants, including algae and the corals, which we usually have in our aquariums, would not be able to live.

Magnesium has another important function since in fact makes maintaining the correct combination of calcium concentration and alkalinity or carbonate hardness possible.

<b> Phosphate</b> Phosphate
Phosphate has several negative effects if present in a too high concentration. First of all undesirable algae growth might result. Making an aquarium an unpleasant sight.
Phosphate also blocks or retards the growth of corals and calcareous algae.
One of the scientific studies shows that a phosphate concentration higher than 0.05 mg/L decreases the growth of calcareous algae by 90%!

Conclusion: >>>

<b>Ammonia</b> Ammonia
Ammonia and ammonium are substances which should be converted rapidly into nitrite followed by nitrate and nitrogen gas.
If this does not happen then the aquarium is not fully cycled or biological processes are not proceeding as they should.

Euro 6,75 Toevoegen
<b>Nitrite</b> Nitrite
Nitrite is a substance that is toxic to fish and invertebrates. It is a misconception that once a tank is through its cycle (first 3 or 4 weeks) that nitrite has vanished. Many nitrite test kits suffer from interference by amines (such as naturally occurring and essential amino acids) resulting in a too low measured value especially if the nitrite concentration is relatively low. Nitrite is converted to nitrate in properly cycled aquariums. The thus formed nitrate is transformed into harmless nitrogen gas (=denitrification). This happens in areas deprived of oxygen within live rock and miscellaneous filter materials.

Conclusion: >>>


Euro 6,50 Toevoegen
<b>Nitrate</b> Nitrate
When an aquarium has insufficient regions deprived of oxygen (= anaerobic zones) or denitrification proceeds incompletely then nitrate will build-up.

A too high nitrate concentration can result in unwanted algae-growth and these might irritate corals in their neighborhood.
Nitrate as such also retards coral growth.
The nitrate concentration in a proper functioning reef aquarium should preferably be lower than 1 mg/L. Fish-only aquariums would usually show much higher nitrate concentrations.

<b>Silicate</b> Silicate
Silicate occurs especially in tap water or in purified water when the RO or DI unit is not functioning properly. Silicate not only results in diatom bloom but might also block some essential trace elements such as vanadium and molybdenum.

Approx. 60 tests per kit. The range is 0.03 - 30 ppm as SiO2.


Euro 7,75 Toevoegen
<b>Strontium </b> Strontium
Strontium plays an important role by accelerating coral and calcareous algae growth. NSW contains approx. 7 – 9 mg/L strontium. Since the growth of corals and calcareous algae goes hand in hand with strontium and calcium depletion, depletion of calcium usually means depletion of strontium as well.

Approx. 25 tests per kit. Measures in approx. 5 ppm increments.


Euro 14,25 Toevoegen
<b>OXYGEN</b> OXYGEN
Oxygen Test
Oxygen is highly essential for all life forms. Especially corals and marine fish require oxygen concentrations at saturation level. This is because of the low solubility of oxygen in saline water which is approx. 5 - 7 ppm.
The oxygen test measures oxygen concentration in just a few minutes.
Approx. 50 tests per kit. Range: 2- 14 ppm.


Euro 7,25 Toevoegen
<b>pH</b> pH
pH Test
The pH value can have a major impact on the growth of corals and calcareous algae and on many biological processes. The pH should not be allowed to fluctuate more than approx. 0.3 units during 24 hours and should preferably be kept between 8.0 and 8.2.
Approx. 50 tests per kit. Range pH 7.4 - 8.6.


Euro 5,25 Toevoegen
<b>IODINE</b> IODINE
Iodine Test
Iodine is present in NSW (Natural seawater) in a very low concentration (0.06 mg/L or 0.06 ppm).
Iodine occurs as different species. Some of them are iodide, iodate and hypoiodite.
Generally when we say iodine then we mean one or more iodine species without a clear distinction being made. NSW contains predominantly iodate and to a slight extent iodide.
Approx. a total of 40 tests per kit. Measures iodide and iodate (together with hypoiodite and molecular iodine) in separate steps.
