The A3 Apex PRO is the perfect surveillance system for you when you:

  • want to monitor your aquarium at any time from any device
  • want to monitor critical parameters, such as temperature
  • want to be notified by SMS or e-mail when the parameters are outside the specifications
  • want to know when the power or Wi-Fi connection to your aquarium is lost
  • want to be alerted of a possible overflow or leakage around your aquarium
  • want to be able to automate equipment to respond to parameter changes or emergency situations

The A3 APEX has the following features:

  • Temperature monitoring

The Apex is a self-contained monitoring platform built for reliability – for when things go wrong – It’s not just a toy to play with when everything is A-OK.



Every Apex has a built in web-server (tech talk for its control software and built-in web interface) with complete functionality – even if the internet is down! This is important, see why. . .

Let’s say you have a power outage and want your aquarium to take the appropriate actions to maintain the fish and corals for the longest time possible. Or, what if the internet is down (or a company’s cloud servers) and you simply want to manually turn on your lights or turn off your skimmer.

Some aquarium devices work ONLY via their online cloud service, so when the internet is down or slow, you are out of luck. With the Apex, even if the internet is down, your tank will continue operating without interruption.
