 | Salifert Profi Test Copper
Copper is often used as a treatment for parasite infested fish and it is essential that the correct concentration is used as too high levels can be toxic to marine fish and invertebrates.Tap water can also be naturally high in copper and it is therefore advisable to test for this on a regular basis.The Salifert test kit offers a very sensitive and accurate test for measuring dissolved or weakly chelated copper from 0.05mg/L to 2mg/L.Lasts for several copper cures or provides sufficient for up to 50 tests on tap or aquarium water as a routine check.

 | Salifert Profi Test Iodine
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.There is however a misconception among many hobbyists that iodide predominates in NSW. This is however false.Test kits which are not capable in detecting iodate might not really be suitable for aquarium use. Since in an aquarium iodide can be transferred to iodate. This means that if a test kit is used not capable in detecting iodate, a false low total iodine concentration (sum of iodate and iodide) will be obtained and the iodate concentration can climb far too high and possibly upsetting the aquarium environment.The Salifert Iodine Profi Test measures all naturally occurring iodine species such as iodate, iodide, molecular iodine and hypoiodite. No other test kit offers this possibility.Salifert’s Natural-Iodine additive is highly concentrated and contains a large portion iodate and also some iodide.Salifert stands alone in offering such an advanced and well thought formulation.Approx. a total of 40 tests per kit. Measures iodide and iodate (together with hypoiodite and molecular iodine) in separate steps.

 | Salifert Profi Test pH
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.If the pH is too low then the cause may be a too low alkalinity and/or insufficient aeration.A low pH can be corrected by improving aeration and by increasing the alkalinity to NSW (Natural seawater) value or upto approx 25% above NSW levels.The Salifert pH test kit is sufficiently accurate to monitor pH fluctuations of approx 0.2 pH units. Our KH + pH Buffer allows fast and efficient correction of alkalinity.Approx. 50 tests per kit. Range pH 7.4 - 8.6.

 | Salifert Profi Test Strontium
Strontium plays an important role by accelerating coral and calcareous algae growth.NSW contains approx. 7 to 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.It is advisable to maintain a strontium concentration between 5 and 20 mg/L.Strontium measurement is a necessity but is unfortunately a relatively difficult test. Perhaps in forthcoming years this will change when newer and easier methods for strontium measurement will become available.It therefore is a test, which many hobbyists will not conduct frequent enough.For that particular reason strontium additives should be designed in such a way that a too low or a too high strontium concentration is avoided.With the Salifert Natural-Strontium additive we have reached this aim.When used in combination with our Coral Calcium additive according to the instructions then the need for strontium measurement is greatly reduced and would have to be performed only once every few months.Furthermore NSW contains strontium associated with sulfate. This form lacks the toxicity, the commonly used, strontium chloride has.We therefore use predominantly strontium sulfate together with some other ingredients to avoid the occurrence of an ionic imbalance. It also makes it more effective and less toxic than strontium chloride.The Salifert strontium test kit detects both ionically free and moderately complexed strontium. Salifert was the first to introduce a strontium test kit.Approx. 25 tests per kit. Measures in approx. 5 ppm increments.

 | Salifert Profi Test 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. The Salifert Ammonia test is very straightforward and measures the sum of toxic ammonia and ammonium in just a few minutes. The kit can perform approx. 50 measurements and can detect 0.5 ppm of total ammonia easily.

 | Salifert Profi Test 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.Before it can be transformed to nitrogen gas the nitrate is first converted back to nitrite. When for whatever reason this particular cycle can not be completed, toxic nitrite can be present in significant concentration and readily be detected by test kits that do not suffer from amine interference.Conclusion:Many nitrite test kits have the potency to suffer from amine interference resulting in toxic nitrite not being detected.Salifert’s Nitrite test kit does not suffer from such an amine interference because very special ingredients are used.These same ingredients also result in a full color development within minutes. The developed color is very intense making detection of even minute traces of nitrite easy. It probably is the most sensitive, accurate and fastest nitrite test kit available.The kit can perform approx. 60 measurements.

 | Salifert Profi Test 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.Most test kits use a procedure in which a certain part of nitrate is converted chemically into nitrite and is measured as such.Once again, just as with nitrite testing, amine interference has a major impact on the measured value. If such an interference occurs concentrations much lower than actual will be measured.Conclusion:Many nitrate test kits are prone to amine interference. This can give results much lower than actual.The Salifert nitrate test does not suffer from such an amine interference. The very special ingredients allow a very fast and precise measurement.The range spans from very low to a very high nitrate concentration (approx. 0.05 to 20 mg/L as Nitrate-Nitrogen or 0.2 to 100 mg/L as nitrate ion).The kit can perform approx. 60 measurements.

 | Salifert Profi Test 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%!Washing fish food, which is a rich source for phosphates in a sieve after thawing reduces the input of phosphate tremendously. Also avoiding use of phosphate-rich low-grade activated carbon helps keep phosphate levels as low as possible. Checking the activated carbon for phosphate prior to use is therefore highly recommended.Elevated concentrations of phosphate can be removed by using an iron based Phosphate-Remover which also decreases silicate and organics content and adsorbs toxic heavy metals.Conclusion: Since phosphate can have major consequences when present in a concentration above 0.05 mg/L a test kit should be able in detecting even lower concentrations.The Salifert phosphate test already detects, within seconds, 0.015 mg/L of phosphate. This makes phosphate measurement highly reliable and informative allowing timely measures to be taken. The kit can perform approx. 50 measurements

 | Salifert Profi Test 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.The explanation is as follows. Calcium forms with carbonates and bicarbonates an insoluble compound called calcium carbonate. Yes this is indeed an important building stone for corals and calcareous algae but then it should be formed by biological processes and be deposited at the right place. Therefore formation of calcium carbonate by chemical processes should be avoided.Even without biological interference calcium carbonate would be formed and would deplete calcium and alkalinity or carbonate hardness without fulfilling any function. In fact it will scavenge many important trace elements as well lowering the trace element concentration.Magnesium slows down this negative process. The lower the magnesium concentration the faster this negative process will take place and also at a much lower calcium and alkalinity/carbonate hardness value.Maintaining a correct magnesium concentration is therefore very important and is indirectly responsible for fast coral and calcareous algae growth by virtue of making the maintenance of correct calcium and alkalinity figures possible.Magnesium is depleted by algae and is also depleted by the use of excessive kalkwasser and by going far beyond natural calcium and alkalinity and pH values.There are also certain brands of salt, which have or had a dramatically low magnesium content. Use of such a salt will result in permanent problems with calcium and carbonate hardness values.Conclusion:The measurement of magnesium and taking corrective measures are justified. Magnesium additives should be such that no ionic imbalance is created. Furthermore many magnesium salts contain sufficient amounts of ammonia to upset biological balances. Very high-grade magnesium salts are therefore required.Magnesium is an element which was neglected for a long time. The magnesium content of some aquariums appears to be rather low when tested. Corrective measures have to taken for a balanced reef system.The Salifert magnesium test is very straightforward and does not suffer from calcium and strontium interferences when within certain bounds. It measures in sufficient accurate steps of 30 mg/L with a sharp color change. The kit can perform approx. 50 measurements.

 | Salifert Profi Test Alkalinity/Carbonate Hardness
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 to 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.NSW has an alkalinity of approx. 2.7 meq/L or approx. 7.5 dKH when expressed as carbonate hardness.For a stable system the alkalinity or carbonate hardness should have a value similar to NSW or slightly higher and should preferably not fluctuate by more than 5%. This means a maximum fluctuation of 0.14 meq/L or 0.4 dKH.Therefore an alkalinity test kit should be capable in measuring in steps smaller than 0.14 meq/L. Conclusion: Since the major buffer components used for coral and calcareous algae growth are bicarbonate and carbonate, they should be added to correct any decrease in alkalinity or carbonate hardness.A proper formulated buffer should function in such a way that the corrective measures results in a long lasting effect and should not upset the pH of the system. The alkalinity or carbonate hardness should be kept as stable as possible requiring highly sensitive and accurate means for testing. The Salifert KH/Alk test is very straightforward. It measures in sufficient small steps of 0.1 meq/L or 0.3 dKH with a sharp color change. This makes detection of important yet small change possible.The kit can perform approx. 100 - 200 measurements.

 | Salifert Profi Test 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.NSW contains 400 to 450 mg/L calcium. Which is also the value we should strive for. For a stable aquarium environment the fluctuation in calcium content should preferably not more than approx. 15 mg/L. This automatically means that the calcium test should be able to monitor comparable fluctuations.Conclusion: In a healthy aquarium growth and multiplication of corals, desired calcareous algae and other organisms results in calcium depletion. Because of the importance of calcium timely corrective measures would have to be taken. For that purpose a proper calcium additive together with an accurate test kit are required.Our calcium test is capable in resolving the calcium content in 10 mg/L steps. The color change is sharp and facilitates the detection of small but highly significant fluctuations in the calcium concentration. Salifert is the only one in offering a true accuracy and precision as claimed.The kit can perform approx. 50 - 100 measurements.
