Why Do I Need an Aquarium Monitor?

An aquarium monitor is a valuable tool for any aquarist. It serves as your eyes and ears, continuously checking and reporting the vital parameters that ensure the health and stability of your aquarium. By keeping track of temperature, pH, water level, and potential leaks, an aquarium monitor:

• Prevents Disasters: Early detection of abnormal conditions, such as temperature, allows for immediate intervention, preventing potential damage and loss.
• Saves Time and Money: Automated monitoring reduces the need for frequent manual testing and can help avert costly repairs from unnoticed issues.
• Enhances Peace of Mind: With real-time alerts and remote access, you can be assured that your aquarium is functioning well, even when you're not home.

Why Should I use the A3 Apex Jr. on my Aquarium?

The A3 Apex Jr is an affordable, entry-level monitoring solution that keeps tabs on only your most essential tank needs. Track temperature and pH plus water level and leak detection to protect your aquarium and home.

The A3 Apex Jr features two AquaBus ports that will allow you to connect additional modules and accessories to continue building out your control system.

What Else Do I get with the A3 Apex Jr?

Aside from the A3 Apex Jr. itself, included in the box are four monitoring probes/sensors that give you temperature, pH, water level, and leak detection.

Temperature Probe: If the temperature falls outside of the specified safe zone, you'll receive a notification so that you can correct the issue. Crucial for detecting malfunctioning heaters early, allowing you to fix the problem before it's too late.

pH Probe: Knowing your aquarium's pH is helpful in a number of ways, but particularly useful if you're dosing two-part or kalkwasser to your aquarium. For example, the pH probe might help you detect a potential overdose due to a stuck dosing pump.

Magnetic Optical Sensor (MOS): This low-profile level sensor can be used for a number of purposes such as a high or low level warning in your sump or dosing container. It can be mounted on any type of material up to 1/4" thick. 

LD-2 Leak Detection Sensor: Protect your floors by placing this sensor inside your aquarium stand or any other flat surface where an overflow may cause issues. If water ever touches the sensor, your A3 Apex Jr. can notify you so you can take action.
