The One Year Alert Combo pack combines a year supply of Ammonia Alert? (1 card) and pH Alert? (1 card and 1 replacement sensor).
Ammonia Alert? and pH Alert? are almost half the size of competing products. At 1.5" x 2.5", they are small, clear, and unobtrusive, so they won't detract from the view of your aquarium.
Simply place Ammonia Alert? and pH Alert? visibly anywhere in the aquarium or filter. It?s that easy. No chemicals or test procedures are required.
pH Alert? is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously. A sensor changes color reversibly from yellow to orange to red alerting you to shifts in pH levels between 5.4 and 8.0.
