Place pH Alert visibly anywhere in the aquarium or filter. It's that easy. No chemicals or test procedures are required. When first put in service, response time will be about 30 minutes. Thereafter, pH shifts will register within ten minutes. The life of the pH Alert sensor may vary depending on a variety of tank parameters. Sensor exhaustion is indicated by a visible fading or washing out of sensor color.
