It's a must-have tool for monitoring water quality and ensuring the well-being of your aquatic life.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 is 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).

This kit is designed to provide accurate results in minutes, helping aquarium enthusiasts maintain a healthy environment for their aquatic life.With its high sensitivity, the Salifert Nitrite ProfiTest Kit can detect even the smallest changes in nitrite levels, making it an essential tool for proactive aquarium management. The kit comes with clear instructions and all necessary components included, ensuring easy use for all users.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. However, if this cycle breaks down, 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. The Salifert Test Kit, with its unique formulation, does not suffer from amine interference, and offers full colour development within one minute. The colour 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.

Wipe it thoroughly with HI-731318 or a lint–free cloth prior to insertion.Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove bubbles by swirling or be gently tapping the cuvette.Do not let the reacted sample stand for too long after reagent is added as accuracy will be affected.After the reading, it is important to immediately discard the sample otherwise the glass might become permanently stained.Supplied with2 sample cuvettesCuvette capStarter pack of reagents x 6 tests (re-ordering information: HI-774-25 x 25 tests)1 x 1.5 AAA batteryInstructionsAlso available to purchase separately: HI-774-11 calibration setFour steps.

This practical handheld Checker covers a comprehensive range of nitrate, with single-button operation for fast testing and no requirement for filtering, providing insight into the nitrate level within your fish tank.The HI-782 nitrate digital tester covers the high range of nitrates in saltwater aquariums, from   0.0 to 75.0 ppm as NO3–. A single, included AAA battery is required for operation, with an additional power-off feature that triggers after 10 minutes of inactivity, prolonging battery life.Why measure nitrate?Nitrate is a key part of the nitrogen cycle, the mechanism where waste produced by the fish and corals are converted from ammonia to nitrite to the end product, nitrate. While nitrate is not toxic to fish in the same way as nitrite, build-up of this parameter can lead to algae, cyanobacteria, and dinoflagellates growth, which may outcompete the coral within your aquarium. High nitrate levels may also indicate higher phosphate levels, leading to odours and staining in your fish tank.Measuring the nitrate level in your tank with the HI-782 digital nitrate Checker allows you to quickly see differences in the levels of nitrates, with clear on-screen digital results. Checkers don’t require personal perception to determine the results of testing fish tank parameters, enabling fast response to make changes for balanced water chemistry in your aquarium. How does the HI-782 work?The HI-782 uses the zinc reduction method for testing, specifically development for use with salt\/seawater and with no requirement to filter the sample before testing, In this method, that reagents provided with the nitrate Checker are introduced to the sample vial, creating a measurable reaction. The reaction between nitrate and the reagent causes a pink tint, which is read by the Checker to provide a digital readout in parts per million. The HI-782 includes a reagent starter kit with reagent for 10 tests, allowing you to start testing nitrate levels in your saltwater fish tank straight out of the box.Four steps to test  1. ‘Zero’ the Checker with your vial \u0026amp; 10 ml water sample inside  2. Take your vial out and add your reagent  3. Place your vial into your Checker  4. Press the button and read the resultsCheckers vs test stripsMany aquarium owners choose test strips as an affordable way to measure key marine aquarium parameters. While testing strips can give a general idea of the levels of nitrate, they require personal perception to determine testing results. Hanna Checkers remove the guesswork required for testing, with a clear, accurate digital display in ppm. Where can the HI-782 Marine HR Nitrate Checker be used?The HI-782 is developed specifically for use in seawater and reef fish tanks.Features:Compact, handheld designAccurate to ±2.0 ppm ±5% of readingDedicated to a single parameterUses a single AAA battery (included with Checker)Power off functionality after 10 minutes of inactivityTimer built-in for timed reactionsOrder Information:The HI-782 Checker is supplied with 2 cuvettes and caps, marine nitrate reagents x 10 tests  (HI-782-25), a 3 ml Pasteur pipette, 1 x 1.5V AAA battery, and an instruction manual.Order more reagents with code HI-782-25 for the HI-782 Marine Nitrate High Range Checker.","brand":"Reef Addiction","offers":[{"title":"Regular","offer_id":64085852979549,"sku":"679532X","price":79.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/1148\/3741\/files\/original_c5895a65-b72c-4a48-910c-6b593833ba78.jpg?v=1775252620"},{"product_id":"hanna-instruments-hi-782-25-marine-high-range-nitrate-checker-reagents","title":"Hanna Instruments HI-782-25 Marine High Range Nitrate Checker Reagents","description":"\u003cp\u003eHI-782-25 Marine High Range Nitrate reagents, 25 tests, for use with the HI-782 HR Nitrate Handheld Colorimeter Checker.\u003c\/p\u003e","brand":"Reef Addiction","offers":[{"title":"Regular","offer_id":64085855142237,"sku":"G643581","price":22.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/1148\/3741\/files\/original_39b6f6c4-bea0-4fa5-a4d0-3df58dca04d4.jpg?v=1775252638"},{"product_id":"hanna-instruments-hi-774-25-reagents-for-the-hi-774-marine-phosphate-ulr-checker-hc-colorimeter-25-tests","title":"Hanna Instruments HI-774-25 Reagents for the HI-774 Marine phosphate ULR Checker HC Colorimeter, 25 tests","description":"HI-774-25 Reagents for the HI-774 Marine phosphate ULR Checker HC Colorimeter, 25 testsThe HI-774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker® HC.These reagents follow the Ascorbic Acid Method in which the reaction between phosphate and reagents causes a blue tint in the sample.By simply adding the packet of HI-774-25 reagent to the sample, the reaction will take place and the HI-774 will determine the concentration from the colour that is produced.The results will be displayed in ppb of phosphate.
