Whenever you need to treat with Copper, a treatment for many parasitic infections, you must also be monitoring the copper level in an aquarium or a pond. The copper level can drop too low for the treatment to be effective, or can increase to a point that is detrimental to fish health. Copper is also likely present in your tap water.

The API Copper Test Kit allows you to easily and accurately monitor copper levels to maintain copper-based fish treatments at therapeutic levels, and tests copper levels from 0 to 4 ppm. The kit measures both free and chelated copper, and is suitable for use in fresh and saltwater aquariums, or with ponds.

Contains 90 tests and includes 1 test bottle, easy-to-ready instructions, glass test tube and colour chart.
