These extensions are designed to extent the neck of Reef Octopus skimmer to achieve greater improvements in filtration and refined control. By adding onto the length of your skimmers neck you increase dwell time achieving greater contact time with dissolved organics and allow for higher internal water height settings. This is an easy way to upgrade the performance of an existing Reef Octopus skimmer without having to purchase a new skimmer.
NOTE: The "Twist & Lock" extensions for the Elite and Prime skimmers are white pvc and& the traditional o-ring extensions are only available in black acrylic.

Great way to boost efficiency!
Posted by Brian on Oct 4th 2019
These things are awesome! I added 7" to my Regal 300 (2 neck extensions). It's pulling nice black sludge. I'm planning on upgrading my tank so was looking for a way to boost the capacity of my skimmer since it's already the biggest one Reef Octopus makes! Fragtastic Reef was also great to work with since the item was backordered but it shipped right when they said it would.
