Explore aquarium water test kits and digital testers at The Tech Den for freshwater, marine and reef setups. Compare multi-parameter kits, individual tests, test strips, digital checkers and replacement reagents according to the water parameters you need to measure.
The API Freshwater Master Test Kit measures pH, high-range pH, ammonia, nitrite and nitrate. Other listed options include API GH and KH tests, Aqua One freshwater kits, Fluval test kits and JBL test strips. Check the parameters included in each kit rather than assuming a multi-test pack measures everything you need. Explore API, Fluval, Seachem and Sera test kits for more options.
Browse API Saltwater and Reef Master kits, Red Sea Marine Care and Reef Foundation Pro kits, and individual Salifert, Aquaforest and NYOS tests. Listed reef-testing options cover parameters such as alkalinity, calcium, magnesium, nitrate and phosphate, with selected tests for copper, potassium, iron, iodine and silicate. Compare Red Sea, Salifert and Aquaforest test kits for your system.
Hanna Checker models offer digital testing for specific parameters, while the Hanna HI98319 measures salinity. Check the exact model, freshwater or marine suitability and measurement range before ordering. JBL ProScan strips provide smartphone-compatible testing. Seachem Alert products offer continuous colour indicators for selected parameters; pH Alert is specified for freshwater use. Browse Hanna test kits to compare digital options.
Find compatible reagents, calibration solutions, test tubes and selected laboratory-test options. Match Hanna reagents to the exact checker code, and distinguish high-range, low-range and ultra-low-range products. Follow the chosen test's instructions, check reagent expiry dates and record results to track changes. Water tests measure the parameters covered by the kit; they do not diagnose every possible livestock or aquarium problem.
