When you want the best for your filtration equipment, the Bubble King Supermarin delivers.


The Supermarin is part of Bubble King's flagship lineup, featuring robust acrylic construction, hand-welded seams, and the Red Dragon 3 Speedy pumps. 


The Supermarin features similar heavy acrylic construction to the DeLuxe, but in a slightly more compact design. The internal cone design compensates for less internal reaction space & dwell time, but does generally result in wetter skimming. The Supermarin is geared towards systems where bioload is high or aggressive skimming is desired. While all BK skimmers are conservatively rated, in the case of the Supermarin, it's especially unnecessary to select an oversized skimmer, and oversizing can often result in inconsistent skimming.


Bubble King has been the gold standard in premium skimmers for decades now. From tiny details like titanium screws and ceramic bearings to premium cast acrylic bodies and Red Dragon pumps, no detail is overlooked in crafting the highest performing skimmer for the hobbyist who demands the best in every aspect of their system. When you buy a Bubble King, you are getting a skimmer that you can count on to deliver years of reliable service.

Product Questions

Can these be used as an external skimmer?
Question by: Matthew Levitt on Nov 11, 2022, 7:10 PM
Thanks for the question! These skimmers are designed for internal sump use only, not for an external application. For external skimmers I recommend look at the Reef Octopus EXT options. Please let us know if we can help with anything else!
