Product Description Hanna Salinity/Temperature Checker - HI98319 Salinity/Temperature Meter - Each meter is supplied with: CR2032 battery (inside the meter), Storage / Protection sleeve, Instruction manual, Quality certificate, and 35.00 ppt calibration standard sachet (4 pcs.) Hanna Nitrate - 781 Checker - Nitrate 0.00 to 5.00 ppm (as NO3–) [0.0 to 50.0 ppm (calculated) using dilution] - The HI781 Checker® HC (Handheld Colorimeter) is a simple, accurate and cost-effective way to measure nitrate in saltwater. Nitrate is a bi-product of ammonia. It comes from fish waste, plant decay, and leftover food. Over time, nitrate can build up in your aquarium. While low levels are not harmful, too much nitrate can be detrimental to the health of your fish and plants. Both odorless and colorless, nitrate can only be detected by testing. Salifert Phosphate - Easily test the phosphate level in your tank. Trusted by discerning reefers for years, Salifert Test Kits feature some of the easiest to read results available to each testing method. The Salifert Phosphate Test Kit contains 60 tests.

Product Description The HI780-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Marine pH Checker® HC. These reagents follow the Phenol Red method in which the reagents produce a range of color that is pH-dependent. By simply adding 5 drops from the bottle of the reagent to the sample, the reaction between the sample and reagent causes a tint in the sample that varies from yellow to red. The intensity of the colour is determined by a compatible photometer and the concentration will be displayed. The results will be displayed in pH units with a resolution of 0.1 pH. Get your replacement reagents for your HI780 Marine pH Checker® HC today. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

Product Description Get accurate water testing results with the HI780 Marine pH Colorimeter. With a digital read out, there is no more struggling to determine colors visually. This pH tester's compact design fits in your pocket or stores easily in your shop. Easier to use and more accurate than chemical test kits. One-button operation makes getting your pH results simple. Great for aquariums and marine environmental testing. The HI780 Checker®HC (Handheld Colorimeter) is a simple, accurate and cost effective way to measure pH in saltwater. pH is a measure of the hydrogen ion concentration in your water; the higher the concentration, the more acidic the water is. A neutral pH is 7; most fish can live in a general range between 6 and 8. Keeping your aquarium pH stable and in optimal ranges reduces stress on your fish and aquatic animals, helping them resist disease and tolerate other stressors. Maintaining an ideal pH can also dramatically improve growth, behavior, and overall appearance. Designed as a more accurate alternative to chemical test kits, the HI780 marine pH meter provides quick, accurate results in a few easy steps. Features at-a-glance: For use with saltwater samples Easier to use and more accurate than chemical test kits Dedicated to a single parameter Small size, big convenience Ideal for aquariums and marine biology applications.

Product Description Nitrification is the biological oxidation of ammonia (ammonium ion) into nitrite followed by the oxidation of the nitrites to nitrates. The first step of this 2-step process is carried out in an aquarium by nitrifying bacteria. During this quick process, the ammonium levels drop while the nitrite levels increase. Since nitrite is just as harmful as ammonia, nitrite levels should be maintained at immeasurable levels. A mature biological filter should be able to keep nitrite levels low.Also, if tap water is to be used in an aquarium, it is recommended that it be tested for phosphate, as well as silicate, ammonia, nitrate, nitrite, pH, and alkalinity.The HI764 Checker® Handheld Colorimeter bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate, while professional instrumentation can cost hundreds of dollars and can be time-consuming to calibrate and maintain. Hanna Checker®’s are accurate, affordable and easy to use.To begin measurements, first, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Checker®, press the button and read the results. It’s that easy.The contoured style of these Checker®’s fit in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.
