Salifert Salifert Nitrate (NO3) Test Kit (Reef)
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 – 20 mg/L as Nitrate-Nitrogen or 0.2 – 100 mg/L as nitrate ion). The kit can perform approx. 60 measurements.

Free ammonia is the toxic form of ammonia (vs. ionized Ammonia NH4+ which is non-toxic) and thus it is much more important to keep an eye on the level of free ammonia in your system. This kit may be used with freshwater or marine water. Unlike other kits on the market, the chemical basis for this test assures that interference from other substances is highly unlikely. MultiTest™ Ammonia performs over 75 tests and contains a reference sample for validation. Features 75 Tests MultiTest™ Ammonia performs over 75 tests And with the multi-cavity test plate, multiple tests can be run at the same time. Seachem Sensor Technology This kit is based on the same gas exchange technology that is used in the Ammonia Alert® and thus is the only kit on the market that can read levels of free ammonia while using ammonia removal products such as Prime®, Safe™, AmGuard™ and any similar competing products. Other kits (salicylate or Nessler based) determine the total ammonia by raising the pH of the test solution to 12 or greater. At this high pH all ammonia removal products will breakdown and rerelease the ammonia, thus giving you a false ammonia reading.

Salifert Salifert Calcium Test Kit (Reef)
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 – 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.

Salifert Salifert Phosphate Test Kit (Reef)
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. 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 Salifert Alkalinity Test Kit (Reef)
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. 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 Salifert Magnesium Test Kit (Reef)
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 Salifert Copper Test Kit (Reef)
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 with a pH of 7.5–9. Lasts for several copper cures or provides sufficient for up to 50 tests on tap or aquarium water as a routine check. Can be used for marine, fresh and garden pond water. Strongly chelated copper will only be partly or not at all detected.

Salifert Salifert Flatworm eXit Test Kit (Reef)
Flatworm eXit itself is quite safe to fish and invertebrates.However, the body fluids of flatworms can be toxic to some reef inhabitants when present in a too high concentration. This body fluid is sometimes excreted when flatworms die.So when you use this product it is important to do the following first1] Siphon out as many flatworms as possible.2] Keep sufficient fresh activated carbon in a canister ready.3] Turn off UV, ozone and remove activated carbon. Keep the skimmer turned on.Important remarksBelow given remarks are a.o. meant to reduce the amount of the flatworm’s toxic body fluids in the water.Many people have treated their reef tank(s) successfully using Flatworm eXit without any problems. The most important factors are reducing the number of flatworms before commencing with the treatment and reducing the amount of the flatworm’s body fluids, released when they die, as fast as possible.Do not underestimate the number of flatworms in your system. In a few cases a significant number of flatworms can be hiding in for example crevices. Blow in such and any other potential hiding places water to blow any flatworm out of there. For that purpose you can use a powerhead or a turkey baster. Siphon out those flatworms as well.Furthermore do not underestimate the amount of toxic body fluids these flatworms can excrete. This can be reduced significantly by really siphoning out the flatworms before commencing with the treatment. Further significant reduction is accomplished by siphoning out as many dead flatworms as you can.Any body fluids released by the dead flatworms in the water has to be reduced further by using about 1 pound of fresh high quality carbon for every 50 gallons. The carbon has to be used in a canister with a sufficient forced water flow.Take sufficient time for treating the tank. That is, do not treat your tank in a hurry. Also take time to monitor your tank for at least 6 hours after the treatment.It is also wise to have at least 25% water ready for a water change if required.Dosage:Read all the above text before commencing with the treatment!- 1 drop for every 4 liters or 1 gallon. The dropper contains approx. 300 drops (10 ml). The dropper cap holds approx. 90 drops.So 1 cap full is good for 360 liters or 90 gallons.Add it in a high flow area of the tank. If you want to treat a refugium only and if it’s volume is too small for using a powerhead then mixing should be done manually.- It should start to work within 30 minutes.- If within 45 minutes no visible death of flatworms occurs add 50% more.- As soon as the flatworms start to die commence with the activated carbon to take out any toxic body fluids. Also see the above given important remarks.- After an hour or so you can turn any UV or ozone on again.

Reef invertebrates, such as corals, crustaceans, mollusks, and even some type of encrusting algae, need calcium to grow and remain healthy. Over time, the calcium level drops as it is used by invertebrates, or as it reacts with excess phosphate. The API® Calcium Test Kit measures calcium levels as low as 20 mg/L to help you keep your reef inhabitants healthy. We recommend that you take a few minutes each week to monitor your aquarium conditions and create a better underwater world for your fish.
