Seachem pH Alert 1 tag

pH Alert is a unique color-changing monitor with a sensor that shifts reversibly from yellow to orange to red, continuously alerting you to pH shifts between 5.4 and 8.0 in freshwater aquariums. No chemicals or test procedures are required.

Key Features

• Continuous Monitoring: Just place it in the aquarium or filter and read the color against the included wheel — no reagents needed.
• Fast Response: Initial response time is about 30 minutes; thereafter, pH shifts register within ten minutes.
• Low Maintenance: No care needed beyond wiping off algae with a soft material.
