The Hydra 32 HD is a reef aquarium LED fixture from Aqua Illumination, the second generation of the long-running Hydra line. It packs more LEDs, more PAR, wider spread and a wider spectrum than the original Hydra 32, with a redesigned optic, a thinner body and a dedicated moonlight channel. Control runs through the MyAI app, and it mounts several ways. It suits reefers lighting a mid-size tank who want app control and a broad spectrum without stepping up to a larger multi-cluster fixture. Owners rate the color and growth, but many note the fan noise and the app's learning curve.

Reefers who run the Hydra 32 HD praise its color, spread and coral growth and like the moonlight channel. Complaints center on fan noise and the MyAI app's learning curve.
The Hydra 32 HD is an LED reef aquarium light from Aqua Illumination. It is a redesigned version of the Hydra line, with more LEDs, a wider spectrum with more channels, and a thinner form factor. TIR lenses shape the light output and improve efficiency. The LED placement and lens geometry blend the light from the clusters to reduce color separation.
The redesigned housing improves efficiency, which reduces the demand on active cooling. The fixture is not waterproof, but its improved water resistance helps it handle the moisture around a reef tank. A dedicated moonlight LED and channel lets you set moonlighting independently to simulate the natural lunar color and intensity.
The light is controlled with the free myAI app over a direct Bluetooth Low Energy (BLE) connection from a smart device. It is compatible with MXM, so it can be controlled wirelessly through Apex and Apex Fusion alongside compatible EcoTech and AI pumps and lights. Additional control options may become available over time.
