The ReefLED G2s benefit from a completely new chipset in their compact arrays, delivering a richer spectrum, and thanks to their new power management feature, they can be tuned from a 10,000K reef-white to a 23,000K blue running at full intensity, which was not available in the G1. Their signature REEF-SPEC Blue has also been augmented with violet and ultra-violet and boosted to 470nm blue at the top of the spectrum, causing fish and corals to truly shine.
The ReefLED G2s are 100% Reef Safe & 100% REEF-SPEC, delivering exceptional coral growth and coloration. Setting the daytime lighting program is now super easy: just set the desired color (8000K-23000K) and intensity for different time periods of the day. In addition, the ReefBeat App now offers 5 color/intensity presets that can be manually activated, including coral photography, UV look and more.

ReefMat is Wi-Fi connected to Red Sea’s ReefBeat smart aquarium eco-system and will notify you if the fleece-mat gets torn or runs out, gives you a head’s up before it needs replacing, and even provide you with a daily usage log.

Complete with an installation kit that includes tube holders, clips and non-return valves you could ever need, the ATO+ proves every last detail has been thought about, something we have come to expect from Red Sea in recent times!
