Best Test Kits & Water Testing Equipment of 2023
Best Selling Saltwater Aquarium Test Kits
It should come as no surprise that Salifert dominates this genre because they have long been the go-to test kit for saltwater and reef aquarium hobbyists. The kits offer great value, are available in a wide range of parameters, and are relatively easy to use. Salifert is the #1 selling test kit brand on our website as chosen by all of you.
Best Water Testing Accessory
The surprisingly convenient Smart Stir is a great little device that helps to thoroughly mix water samples with reagents. No more losing the tiny vial caps and you can ensure consistent results with each and every test. It accepts the most common test kit cuvettes or vials and features a rechargeable lithium-ion battery.
Best Magnesium Test Kits
In terms of the best seller, Salifert takes the cake which is going to be a common theme across all of the parameters because of the great value this brand provides. For those who want to ensure more consistent results, we have found the Aquaforest Magnesium kit to be among the easiest to perform while still providing very consistent measurements.

Best Calcium Test Kits
Once again, Salifert is far and away the customer favorite based on the number of test kits sold this year. With that in mind, the Red Sea Calcium Pro rises to the top of this category for the quality materials, consistent results, and easy step-by-step testing process.
Best Alkalinity Test Kits
While Salifert is the most popular "manual" test kit, Hanna Instruments dKH Checker Colorimeter is what deserves attention in this category. Their Checker Colorimeters have really changed the testing game because they provide quick, accurate, and consistent results with minimal room for human error. The dKH Colorimeter specifically is by far the most popular of the Checker Colorimeter lineup because alkalinity is one of the most critical and volatile parameters in a reef tank. Frequent testing with accurate results is the only way to verify the stability a healthy tank needs.
Best Phosphate Test Kits
Similar to the previous category, phosphate is a popular test for reef tank owners and while Salifert wins the affordability prize, the Hanna Instruments Colorimeter is a more impressive contender. Phosphate is maintained at very low levels in the aquarium and at these low ranges, accuracy is difficult to achieve for most any kit. While most hobbyists will simply look for trends in their results, the Hanna Low-Range Phosphate Colorimeter provides a level of accuracy and consistency that can't be had with traditional water tests.
Best Nitrate Test Kits
Breaking the mold, Nyos rises to the top of the Nitrate category because their color reference style nitrate kit is much easier to read than most of the other test kits on the market. Nitrate is one of those parameters that doesn't need to be monitored precisely but rather maintained stable; the key is to avoid perpetually rising nitrate levels and the Nyos kit is most certainly a capable indicator for most home aquariums. Hanna Instruments also deserves a mention in this category because their High-Range Nitrate Checker is the ONLY digital nitrate tester on the market and simplifies the testing process.
