Description

A two in one water chemistry kit for freshwater tanks. It measures the pH of your aquarium water and gives you the means to bring that reading back where it should be for fish and plants.

The box holds a liquid pH test solution with a capped glass test tube, API pH Up and pH Down solutions for raising or lowering pH, and a clear colour comparison chart with instructions. Reagents are enough for up to 250 tests, so routine checks are covered for months or years. Suited to hobbyists and dedicated aquarists alike.

Key benefits

  • Reads aquarium pH across a range of 6.0 to 7.6, a safe and steady window for most freshwater fish
  • Includes solutions to lift or lower pH after water changes, new additions or biological shifts
  • Steady pH lowers stress, supports healthy metabolism and helps avoid long term health problems
  • Plenty of tests for regular monitoring, with weekly checks recommended so changes are spotted early
  • Suits freshwater aquariums of any size, for the benefit of fish, plants and beneficial bacteria

How to use

Test the water using the liquid solution and glass test tube, then compare the colour against the chart supplied. If the reading is off, use pH Up or pH Down to correct it. Follow the instructions included in the kit. Weekly testing is recommended.
