A skimmer overflow, a dry-running pump, and a runaway heater are three completely different failure modes, and AutoAqua builds a dedicated optical-sensor guard for each rather than one catch-all device.
Choosing a Guard
- Smart Skimmer Security - stops protein skimmer overflows before they happen, using a compact optical sensor mounted in the skimmer cup to detect rising skimmate and cut power before it spills.
- Smart Level Security - protects any pump-fed equipment from running dry or overflowing by monitoring water level with an optical sensor and cutting power outside the safe range.
- Smart Temp Security - protects your tank from a malfunctioning heater or chiller by cutting power the moment temperature drifts outside a set safe range.
Why Dedicated Guards Beat One General Sensor
Each of these failure modes has different physical characteristics - skimmate rising in a cup, water level in a reservoir, or temperature drift - and a sensor purpose-built for each specific job responds faster and more reliably than a generic all-purpose alarm.
Setup Tips
- Layer multiple Security devices across different equipment rather than relying on just one - each protects against a different specific failure.
- Test each unit's cutoff behavior after installation to confirm it responds as expected.
- Position sensors precisely per manufacturer guidance for accurate detection.
