WIRELESS INTERNET-READY!
When feasible, we advise using a wired network connection for your Apex or Apex Pro, but if that is not possible, your Apex or Apex Pro may be linked to WiFi just well.

Therefore, we put in numerous man hours to create an amazing 802.11g/n Wi-Fi connection for this Apex that has dependability on par with a cable connection. Additionally, connecting to your home network is quite easy, and it only takes a few minutes to get set up and connected to the Apex Fusion cloud service.

Temperature ProbeThe health of your residents depends critically on maintaining a constant and steady temperature in the aquarium. It is important to continuously monitor the temperature, particularly when it varies throughout the day. For an aquarium to be successful, you must have a reliable temperature monitoring system that also warns you when temperatures are too high or too low.
INCLUDED WITH ![]() |
pH ProbeHealthy coral in a reef aquarium depends heavily on maintaining a constant pH. All of the aquarium’s occupants experience less stress when the pH remains steady. Monitoring pH acts as a crucial early warning system to alert you to harmful chemical changes in addition to allowing you to tune in desired parameter stability.

ORP ProbeWater purity is gauged by something called ORP, or oxidation reduction potential. The ORP level infers subtly that the beneficial bacteria in the aquarium might lessen toxins like nitrates and ammonia, among others. In the end, it is a measure of the electrical charge that is available to disintegrate these pollutants. Unexpected fluctuations in ORP are frequently indicative of harmful organic events occurring in the aquarium. The shift in ORP can serve as a crucial signal to look into or take action if a fish passes or if there is an abundance of food.

Optical Leak SensorAn upgraded variant of the Solid-Surface Leak Sensor is the Optical Multi Surface Leak Sensor. (LD-2). Improvements include an epoxy construction that enables the sensor to be used frequently and an optical sensor that enables placement of the sensor on any surface—including metal and epoxied cement floors—without causing a false activation.

Solid Surface Leak SensorWhen it comes to water on the floor, time is critical. Upon contact with liquid this sensor will communicate to your Apex to send an alert or trigger other actions. With a wire length of 5 meters (16.3ft) this sensor is a must have for placement inside and outside of your sump. Protect your aquarium and your home

Optical SensorConsider a clever float switch. Water above or below the sensor site is detected by the optical sensor. The Magnetic Optical Sensor now has a better appearance and feel. The rapid and simple mounting is made possible by the sealed enclosure, which keeps out water, and the magnetic mounting system.

Liquid Level Sensor (LLS)How much water have you put in? How much remaining solution? Up until recently, the only way to determine it was by taking a measurement. Aquarists now have a brand-new tool that is only available from Apex: the capacity to precisely assess water depth in inches or millimeters. There is a great length for water level monitoring in aquariums, reservoirs, and liquid containers, and it is available in four distinct sizes: 4′′, 15′′, 23′′, and 35′′. Utilize the LSS to advance level monitoring.
