API Phosphate and GH & KH Test Kits for Freshwater Aquariums, 64 Ounces Phosphate and 2.5 oz GH & KH

This aquarium water testing bundle contains two complementary test kits to help aquarium owners monitor and maintain ideal water conditions. The API Phosphate Test Kit (64 oz) accurately measures phosphate levels between 0-10 ppm in freshwater and saltwater tanks. It contains enough testing solution for 150 tests. By monitoring phosphate levels, excess algae growth can be prevented which causes fish stress and inhibits hard coral growth. The API GH & KH Test Kit (2.5 oz) measures both general hardness (GH) and carbonate hardness (KH) levels, important for duplicating fish and plant natural habitats. By matching water hardness, fish stress is reduced. The KH test also helps detect pH shifts. The kit contains enough testing solution for ~100 tests. Used together on a weekly basis, these easy-to-use test kits form a comprehensive water testing bundle that helps prevent invisible water quality issues like excess nutrients, rapid pH changes, and hardness mismatches. This allows aquarium owners to maintain safe, stable water parameters resulting in healthier fish and aquatic life. The bundle is suitable for both freshwater and saltwater aquariums.
