Aquarium problems can get serious fast. Power loss, equipment failure, leaks, temperature changes, or unstable water conditions can threaten livestock and property before anyone notices.
FishGuys Aquarium Monitoring helps catch problems between service visits — even when you’re away.
Monitoring starts at $12/month for members ($14.99/month standard)
Choose essential Safety Monitoring, combine Safety + Water Quality for broader protection, or select Water Quality Monitoring on its own.
| Protection Level | What It Does / Best For | Pricing |
|---|---|---|
| Good Safety Monitoring |
Watches for critical aquarium problems including
temperature changes, leaks, high or low water levels,
power loss, and system outages.
Best for any aquarium type that needs affordable 24/7 early warning of sudden equipment or system failures. |
$12/mo — Member Rate $14.99/mo — Standard Rate $49–$99 starting equipment package or
$24.99/mo — Full ServiceInitial monitoring equipment included + covered equipment replacement |
| Better Water Quality Monitoring Available alone or combined with Safety Monitoring |
Continuously tracks important water conditions including
pH, salinity/specific gravity, ORP, temperature, EC, and TDS.
Best for freshwater, saltwater, and simple reef systems that benefit from early warning of changing water-quality trends. Add Safety Monitoring for broader protection against leaks, water-level problems, power loss, and system outages. |

Designed for advanced reefs, high-value livestock, and automated aquarium systems that need deeper monitoring, remote troubleshooting, and equipment control.
Advanced monitoring and control of aquarium water conditions, pumps, heaters, ATO systems, dosing, power, equipment, and automation.
Additional Apex probes and modules can expand monitoring to leaks, water level, salinity, ORP, equipment performance, and automated water testing.Available capabilities depend on the monitoring equipment, sensors, probes, modules, power, and connectivity installed. Combined starting-equipment pricing reflects both Standard Safety and Water Quality starter packages. Monitoring helps identify aquarium problems but does not automatically include on-site emergency service, repairs, parts, travel, or additional labor unless separately covered.
Best for any aquarium that needs early warning of leaks, temperature problems, water-level changes, power loss, or equipment issues.
Choose the lower-cost plan with purchased equipment, or Full Service with equipment and covered replacement included.
Best for systems where continuously watching water chemistry and changing trends provides additional protection.
Full Service includes the monitoring probe, calibration, and covered probe replacement.
Best for advanced reef, high-value, or automated systems that benefit from deeper monitoring, equipment control, and remote troubleshooting.

Available capabilities depend on the monitoring equipment and sensors installed. Apex features such as leak detection, salinity monitoring and automated water testing may require additional modules, probes or equipment. Monitoring does not automatically include on-site emergency response unless separately covered.
FishGuys can review supported monitoring information and help determine what may be happening.
Some issues may be handled remotely. Others may require someone at the aquarium or an on-site service visit.
Monitoring identifies problems; it does not automatically include emergency visits or corrective service unless separately covered.
