Our Verdicts
AutoAqua Smart ATO Lite SATO-280P Auto Top Off System
The AutoAqua Smart ATO Lite is the first piece of equipment every new reefer should buy. Evaporation is the #1 parameter killer in reef tanks, and this $99 device solves it permanently. Dual optical sensors mean it won't overflow, magnetic mount means zero hassle, and it just works. Essential gear.
Kessil A360X Tuna Blue LED Aquarium Light
The Kessil A360X delivers the most natural-looking light in reef keeping. The shimmer effect from its Dense Matrix LEDs is stunning, and the wide 30x30" spread means fewer fixtures per tank. If you value aesthetics and clean design over granular channel control, the A360X is the premium choice.
