Review on AquaIllumination Prime Reef Aquarium Black by Milton Wolf

Pros - Excellent brightness and spectral coverage. I suggest using the AB+ preset (can be found on various forums and facebook groups). Able to grow the most difficult of corals with the right size and spacing. The fan runs as needed, the puck is generally quiet. I answer Cons. The latest firmware updates have reduced the maximum brightness (before it was possible to significantly exceed 100). This was due to lens burn-in (LED is fine, only cover may warp). The lens can also warp during firmware updates. Nevertheless, these small and simple repairs "burn out". The AI responded incredibly quickly to sending replacements. As long as the device is well ventilated, has a brightness below 100% and is clean, this problem should not occur. Other thoughts: I highly recommend getting a 3D reef diffuser cover. This reduces the peak brightness slightly, but mixes the spectrum and reduces the "disco ball" effect.
