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.
Reef Octopus Classic 150-INT Protein Skimmer
The Reef Octopus Classic 150-INT is the most recommended mid-range skimmer in the hobby for good reason. It pulls consistently, breaks in quickly, and doesn't break the bank. If your tank is under 150 gallons and you want set-and-forget skimming, this is the one.
