Seachem Alert Combo

The Alert Combo™ package combines Ammonia Alert® (1 card) and pH Alert® (1 card). 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 harm the view of your aquarium. Simply place Ammonia Alert® and pH Alert® visibly anywhere in the aquarium or filter. It's so easy. No chemicals or testing procedures are required.
