What is a Red Sea Reefer DC Skimmer?

Red Sea Reefer DC Skimmers are quiet, efficient skimmers featuring revolutionary self-levelling technology that prevents over-skimming and full cups from spilling while continuing to aerate the water. The Reefer DC Skimmer also features a PSK DC pump, proportionally sized venturi, a bubble diffusor and reaction body that optimises air to water contact time and creates the optimal waste removal environment.

Reefer DC Skimmers are exceptionally quiet due to the PSK DC pump, rubber connectors and an air intake silencer. The skimmer also comes with a dual-action solid-state sensor that monitors foam wetness and waste level, allowing the ReefRun Dual Controller (sold separately) to regulate the DC pump accordingly.

The self-levelling feature of the skimmer is activated when the wetness of the foam in the skimmer neck exceeds the user-adjusted “over-skim” threshold. The intensity of the pump is immediately reduced to prevent the over-skim and then carefully and gradually increased or decreased (according to the foam’s wetness), until the pre-set pump intensity is reached and stable skimming is restored.

What is the ReefBeat App?

The ReefBeat app is the single interface for all Red Sea smart devices. All products in the ReefRun family can be combined into your existing ReefBeat ecosystem for more efficient reef keeping. ReefBeat allows you to fully control your ReefRun system from the palm of your hand, providing you with extra peace of mind - just a quick glance will update you on the status of all your devices.

On the ReefBeat App you can create your unique Feed scenario by switching selected pumps off or run them at different intensities at different times for different durations. Select the order and timing between switching devices back on after a maintenance shutdown, such as allowing a few minutes for your return pump to restore water levels in the sump and aquarium before switching on the skimmer, wave pumps and dosers.

What other Red Sea products can I use with these skimmers?

All parts of the Red Sea ReefRun family are sold separately so that you can completely customise your aquarium water management system to meet the requirements of your personal set-up. The ReefRun Family consists of:

If you require a traditional aquarium water management system featuring a controller, skimmer and pump, we have also created convenient pre-made kits.
