Lose your instructions? They can be found under the documents tab!Calcium is a major constituent of coralline algae, the skeletal material of hard corals and the skeletal needles of soft/leather corals. In many cases too low a calcium concentration retards coral and coralline algae growth. Calcium also fulfills many important biological functions. In a healthy aquarium, the growth and multiplication of corals, calcareous algae and other organisms can result in calcium depletion. To maintain a stable environment it is important that the calcium content should not fluctuate by more than 15 mg/L from the optimum range of 420 - 450 mg/L so regular testing should be carried out. This means that any calcium test used should have an accuracy of significantly less than 15mg/L otherwise it will be difficult to monitor such fluctuations. The Salifert test kit measures in steps of 5 mg/L and has an accuracy of 10 mg/L. The color change is precise, detecting small but significant fluctuations in the concentration of calcium. The test is not affected by magnesium. Sufficient for 50-100 tests. Can be used for marine water, freshwater and garden pond water

Lose your instructions? They can be found under the documents tab!Magnesium is present in natural sea water in a fairly high concentration (1350 - 1500 mg/L) and is an essential element of chlorophyll which is necessary for photosynthesis. Without photosynthesis plants, algae and coral would not be able to survive. Magnesium also helps to maintain the correct combination of calcium concentration and alkalinity as it slows down the formation of calcium carbonate which can absorb many important trace elements within the aquarium. Maintaining a correct magnesium concentration is therefore very important and is indirectly responsible for fast coral and calcareous algae growth by making it possible to maintain correct calcium and alkalinity figures. Magnesium is depleted by algae growth and also by the use of excessive kalkwasser or by going far beyond natural calcium, alkalinity and pH values. The Salifert Magnesium Profi-Test is easy to use and accurate with measurements in steps of 30 mg/L. Results are not affected by strontium and calcium interference. Can be used for marine water only. Calcium and strontium will not interfere when their total concentration is between 200 and 650 ppm. This is mostly the case. Up to 50 tests.

Lose your instructions? They can be found under the documents tab!Calcium is not the only substance needed to form the skeletal material of corals and allow calcareous algae to grow. Carbonate and bicarbonate are also needed and these two substances can have a major effect on stabilizing or buffering pH levels in the aquarium in the correct range of 8.1 to 8.4. The total carbonate and bicarbonate concentration is also called alkalinity or carbonate hardness and for a stable system the alkalinity should not fluctuate by more than 5% from the optimum level of approx. 2.8 meq/L i.e. a maximum fluctuation of 0.14 meq/L. The Salifert test is sensitive enough to detect small changes in levels of alkalinity, measuring in steps of 0.1 meq/L and demonstrating a very sharp color change. Sufficient for 100 to 200 tests. The Salifert KH + pH buffer additive makes correction of the alkalinity or carbonate hardness simple and does not upset the pH of the system Can be used for marine water, freshwater and garden pond water

Lose your instructions? They can be found under the documents tab!When there are insufficient areas of a tank which are deprived of oxygen (anaerobic zones) or denitrification is not taking place properly, nitrate will build up. This can also happen in an aquarium where the biological loading on the system is causing an imbalance e.g. if there is excessive livestock for the aquarium volume or over feeding is occurring. The build up of nitrate can result in unwanted algae growth and the slowing down of coral growth. The nitrate concentration in a reef aquarium should be lower than 1 mg/L, although fish only aquariums would usually have a higher concentration. Just as with nitrite, many nitrate test kits are prone to amine interference which can make the levels of nitrate appear much lower than they actually are. The Salifert test kit does not suffer from such interference and gives accurate and quick results with a total testing time of less than 3 minutes. The test kit's range goes from a very low to a very high nitrate concentration (approx. 0.2 - 100 mg/L as total nitrate). Sufficient for 50 tests. This test offers two ranges: Low range: 0.2 - 10 mg/L (ppm) as nitrate. Medium range: 2 - 100 mg/L (ppm) as nitrate. Clean test vial and scoop after use. Store this kit in a dry place.

They can be found under the documents tab!In a properly cycled aquarium, nitrite is converted to nitrate and then, if there are areas deprived of oxygen such as in live rock and other filter materials, this nitrate is converted back to nitrite and then transformed into harmless nitrogen gas. If this cycle breaks down then nitrites, which are extremely toxic to fish and invertebrates, can form in high concentration. Many nitrite test kits suffer from interference caused by amines e.g. naturally occurring and essential amino acids. This can result in a too low measured value, especially when the nitrite concentration is relatively low. Because of its unique formulation, the Salifert Test Kit does not suffer from amine interference, and offers full color development within one minute. Also, the color is very intense making the detection of even minute traces of nitrite easy. The test kit has two different scales: an ultra-low scale for nitrite-nitrogen which ranges from 0.002 - 0.12 mg/L, and a medium scale for nitrite-nitrogen which ranges from 0.02 - 1.2 mg/L. Sufficient for 50 tests. Can be used for marine water, freshwater and garden pond water

Hanna Marine pH Checker Handheld Checker for Marine pH - HI780 The Marine pH Checker bridges the gap between simple chemical test kits and professional instrumentation.Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. This level of instrumentation also offers greater resolution and accuracy, but can cost hundreds of dollars.The Hanna Marine pH Checker uses the Colorimetric adaptation of phenol red method in marine applications to measure the pH value.. With a digital read out there is no more struggling to determine colors visually. Hanna Marine pH Checker Features Designed to accurately determine nitrate levels in aquariums and other marine environments. Requires only one reagent Compact and Portable Design. Built-In Timer One Button Operation Easier to use and more accurate than chemical test kits Dedicated to a single parameter Hanna Marine pH Checker- HI780 Specifications Range: 6.3 - 8.6 pH Resolution: 0.1 pH Accuracy: +/- 0.2 pH Light Source: LED @ 525nm Light Detector: Silicon Photocell Method: Colorimetric adaptation of phenol red method Operating Environment: 0-50 degrees Celsius, RH max 95% non-condensing Battery Type: 1 - 1.5v AA Auto-Shutoff: Automatically shuts off after 10 minutes of non-use.

Many aquarists have reported that a low potassium value reduces colors in corals. This can be corrected by increasing the potassium value to the normal natural concentration.Now you can accurately measure this value with the new Salifert Potassium Reef Test kits. The Potassium test can be performed in about 90 seconds. This tritatic test kit has a sharp color change, going from yellow to blue, when you hit the level in the sample.This kit is good for 40 tests.
