The API® AMMONIA TEST KIT measures ammonia to help prevent fish loss, as ammonia is the number one stressor and killer of tropical fish. Ammonia is released into an aquarium in the forms of uneaten food, decaying organic matter, and when fish release it through their gills, urine, and solid waste. The API AMMONIA TEST KIT is a mercury-free, salicylate test for fresh and saltwater fish, and measures ammonia levels from 0 to 8 ppm.

• Suitable for Freshwater & Saltwater aquariums
• Helps to accurately keep track of ammonia levels
• Easy to use kit with quick results
• Use during regular fish care, addressing water problems, or setting up a new aquarium

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 for use in fresh and saltwater aquariums, or with ponds.

Copper – a treatment for many parasitic infections – must be monitored 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 likely even present in your tap water.
