Explore API aquarium and pond water test kits at The Tech Den. Compare freshwater, saltwater, reef and pond master kits, individual parameter tests, 5-in-1 test strips and replacement test tubes. Choose tests for your water type and the parameters you need to monitor.
The API Freshwater Master Test Kit measures pH, high-range pH, ammonia, nitrite and nitrate. The Saltwater Master Test Kit measures high-range pH, ammonia, nitrite and nitrate. The Reef Master Test Kit measures calcium, carbonate hardness (KH), phosphate and nitrate. Each kit covers a different set of parameters, so check the contents rather than assuming a master kit tests everything.
Browse ammonia, nitrite, nitrate, phosphate, copper, calcium, GH/KH and separate KH tests. Freshwater pH options include a 6.0–7.6 kit and a high-range 7.4–8.8 kit; a selected pH kit also includes pH Up and pH Down fluids. The combined GH/KH kit is described for freshwater, while the separate KH kit is listed for freshwater and saltwater. Check each product's water-type suitability and measurement range before ordering.
API 5-in-1 test strips are listed in 25-strip and 100-strip packs and measure pH, nitrite, nitrate, general hardness and carbonate hardness. They do not include an ammonia test among these five measurements. A single replacement API test tube is also listed for use with compatible API test kits.
The collection includes the API Pond Care Wide Range Liquid pH Test Kit and Pond Care Master Test Kit. The pond master listing identifies wide-range pH, ammonia, nitrite and phosphate tests. Compare pond-specific contents with aquarium kits to select the measurements you need.
Follow the exact kit's sampling, reagent, timing and colour-chart instructions, and check storage and expiry guidance on the packaging. Use the appropriate chart for your water type and record results to track changes. Water tests measure specified parameters; they do not identify every possible cause of a livestock problem.
