API GH & KH Freshwater Aquarium Water Test Kit Bundle Nitrate 90-Test Aquarium Test Kit

Keep your freshwater or saltwater aquarium water clean and safe for fish with this bundle of two API water test kits. The API GH & KH Test Kit allows aquarium owners to monitor and maintain proper mineral levels, while the API Nitrate Test Kit detects harmful nitrate buildup. The GH & KH Test Kit contains two test bottles, two capped tubes, and instructions to accurately measure your aquarium's general hardness (GH) and carbonate hardness (KH) levels. Proper water hardness helps reduce fish stress and matches their natural habitat. The Nitrate Test Kit includes one test bottle, one tube, a color card, and manual for detecting nitrate from 0-160 ppm. High nitrate can encourage algae growth and pollutant buildup, harming your fish. Used together on a weekly basis, these easy-to-use test kits form a comprehensive water quality monitoring system. By proactively checking GH, KH, and nitrates, aquarium owners can identify and prevent dangerous chemical imbalances, creating a safe, thriving environment for freshwater community fish, cichlids, goldfish, and more.
