The majority of water issues are not evident to the naked eye. With the API FRESHWATER MASTER TEST KIT, you can quickly measure and change the six aquarium levels that are most critical to the health of your freshwater fish. To be healthy and prosper, fish require appropriately balanced levels of ammonia, pH, high range pH, nitrite, and nitrate. When fish waste, uneaten food, or other organic matter accumulates, or when untreated water is supplied, these levels can shift quickly and produce hazardous situations. If left untreated, any of these can be damaging or even deadly to fish, resulting in less oxygen, increased stress, and a higher chance of illness. The API FRESHWATER MASTER TEST KIT accurately measures these six factors and offers expert findings. It includes four glass test tubes, a holding tray, a test tube rack, and a color card that has been computer calibrated and laminated. Fill the test tubes with test drops, then compare the findings to the color card. Then, if action is necessary, follow the advice on the card.
