Our Verdicts
Neptune Systems Apex A3 Pro Controller System
The Neptune Apex A3 Pro is the nervous system of a serious reef tank. It monitors everything, controls everything, and alerts you before problems become disasters. The price is significant, but consider what you're protecting — $3K-10K in livestock and equipment. For SPS keepers, the Apex isn't a luxury. It's insurance.

The DC pump control lets you fine-tune performance, and it handles up to 317 gallons on just 16 watts. If you want the best skimmer technology and don't mind paying for it, Tunze delivers.
