Easy Digital Testing with Precise Results for Reef Tanks

If you ask anyone what are the most important parameters to monitor in a reef tank for good coral growth and health, pretty much everyone will answer with Calcium, Alkalinity, & Phosphates. Hanna Instruments HIREEF2 Test kit includes everything you need to digitally monitor your saltwater aquarium's vital elements, and also a digital temperature and salinity testing pen. Using a digital colorimeter style test kits ensures that the readings can be repeated time and time again without having to worry about outside elements like the lighting in the room, viewing angles, etc. Each test only takes a couple of minutes and when it is finished the results are printing out on a large LCD display that is clear and easy to read.


HI772 Marine Alkalinity (dKH) Checker

Simple, easy, and accurate the Hanna HI772 Alkalinity Checker is our top choice for an alkalinity test kit. If we were to suggest testing a single element every day, it would be alkalinity. Each test only takes a minute and with daily monitoring, you can easily know what is going on inside your aquarium and how your coral is growing. Providing readings in a DKH value makes recording easy without any conversion charts needed.

HI758 Marine Calcium Checker

Every successful reef tank requires a quality calcium checker, and the Hanna HI758 is up to the task. With a straightforward testing procedure, a mechanical pipette, and now including HI70436m Deionized Water reliable calcium readings are only a couple of minutes away. Knowing your reef tanks calcium level is very important, and improper levels can lead to slower calcification of the coral's skeleton, and we all want our corals to grow as fast as possible.

HI774 Ultra Low Range Phosphate PPM Checker

The HI774 Ultra Low Range Phosphate Checker is a cost-effective way to measure phosphate in marine systems, including reef tanks. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp stony. In addition, high phosphate levels can cause nuisance algae growth in your reef tank. This can become problematic because algae often outcompete sessile organisms for light, nutrients, and space, jeopardizing long term coral health in your reef. Testing for phosphates is standard practice for saltwater aquariums and provides valuable insight into your reef tank’s water chemistry to help ensure long-term coral health.
