Freshwater Master Test Kit is a complete kit for testing aquarium water.Tests water 6 different ways to protect tropical fish from dangerous water conditions.Tests include: freshwater pH, ammonia, nitrite, high range pH, and nitrate, 4 test tubes, tray.
Quickly and accurately tests pH of pond or tap water. Proper pH control is necessary to prevent harmful effects of water too alkaline or too acidic. Quickly and accurately tests for pH levels from 5.0 to 9.0. Performs 160 tests.
Ammonia Alert is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year and replacement sensors are available. Marine or freshwater use..
This kit measures inorganic phosphate to less than 0.05 mg/L, producing a unique easy to read yellow-green-blue color range in marine and freshwater. MultiTest™ Phosphate performs over 75 tests and contains a reference sample for validation.
This test kit features a unique dye that has a pronounced color change between 8.0 and 8.3, making it the easiest kit on the market to read in that critical range. Alkalinity may be read from the same sample in 0.5 meq/L increments. MultiTest™ Marine pH & Alkalinity performs over 75 tests and contains a reference sample for validation.
Salicylate test measures ammonia levels in both fresh & saltwater aquariums. Ammonia, the #1 killer of tropical fish, is continually produced in the aquarium from fish waste & uneaten fish food. Tests ammonia levels from 0 to 8 ppm.
