Blue Thumb Serenity Waterfall Filter w/ bio-twist media

The Blue Thumb Serenity Waterfall Filter (PB1151, formerly part of the Serenity Falls line) is the entry-level DIY pond waterfall box, sized for new or existing ponds and water gardens up to 1,200 gallons. It biologically filters and aerates the pond water — beneficial bacteria colonize the included Bacti-Twist media for biological filtration, while a Matala filter mat handles mechanical polishing of debris.

The filter ships complete with a detachable weir, biological filter mat, Bacti-Twist media with net, 1.5" plumbing fittings, and installation instructions. Made in the USA and backed by a 5-year manufacturer warranty.
