Reef Octopus Regal Skimmers now incorporate the new VarioS S pinwheel series of pumps. The new pumps are DC powered allowing for several advantages over traditional AC style pumps. The VarioS pumps can be fully controlled by a 3rd-party controller, or through the included control unit. With 5 different preset speeds and multiple feed modes, you can fine-tune Regal skimmers for superior performance on your particular system.


Space saving protein skimmers have the pumps encased within the body of the skimmer creating a much smaller footprint requirement. These types of skimmers are normally a slight bit taller than their counterpart, the increased height maximizes the amount of contact/dwell time and reaction chamber size allowing for greater filtration capabilities.

Hi, what is the size of the lid?
Question by: Ron White on Dec 4, 2023, 8:30 AM
The lid size would be similar in size to the body, about 6".
Answer by: Laura (BRS Staff) on Feb 7, 2024, 9:28 AM
How would this skimmer work for a 90 gallon tank with the sapphire sump 26.
Question by: Sven Pflug on Nov 22, 2022, 11:32 AM
Thanks for reaching out! This would be the perfect set up!
Answer by: James Johnson (BRS Staff) on Nov 26, 2022, 11:45 AM
This would be an AMAZING option for a tank this size and in fact more than likely you could run this at 40-80% speed to expand the life of the motor.
Answer by: Tyler Schafer (BRS Staff) on Nov 26, 2022, 11:45 AM
Would this be to big of a skimmer for a 72 gallon tank?
Question by: Sven Pflug on Jul 16, 2022, 9:20 AM
Thanks for question! This skimmer will be a bit over sized, but assuming you are using filter socks and not a fleece roller this will be fine. Being it's DC you can dial it back a little to dial it into the slightly smaller tank volume that you have. Let us know if we can help with anything else!
Answer by: Kyle Thomas (BRS Staff) on Jul 18, 2022, 4:08 PM
How difficult is this to integrate with the Apex. You say Apex ready but that is not very helpful. I have a 110 gallon mixed reef tank with a Eshopps Ar-100 sump.
Question by: Dan Fain on Nov 24, 2021, 8:21 AM
Hello. To connect the Regal 150SSS you would simply connect the pump controller to the Apex using this cable:
You can control the pump using the 0-10v function on the Apex to control the pump.
