If true craftsmanship and build quality are your top priorities when selecting a protein skimmer for your aquarium, you can’t do better than an Ultra Reef. The moment you hold an Ultra Reef Skimmer in your hands, you know you’re holding something of lasting quality and performance. The Borei skimmer was built to be compact yet powerful. Ultra Reef cuts no corners and every component is well thought out and precisely machined from premium materials. 


The entire UKB skimmer rotates on its base to open and close the regulation valve, making water level adjustments easy in tight spaces. Its pump features an user-friendly controller which allows for speed adjustments, 5 minute "pause" mode, and a 60 second "delayed start" after blackout. All skimmer components are modular and feature Easy Flip gaskets, making dissasembly for thorough cleaning a breeze.

Product Questions

Is there a drainage port on this so it can be hooked up to the RO waste collector or Avast Skimmate locker? Also, does Ultra Reef make it possible to buy replacement collection cups?
Question by: Matthew Turbin on Dec 19, 2023, 12:20 PM
Hey there, on this unit it does not come with a drainage port although you could modify on your own to create one! Thanks.

Does it have a 1-10vdc control input??
Question by: TOM on Feb 4, 2023, 4:42 PM
Thanks for the question! This only has the connection ports for its own separate controller!
