Choosing an External Filter for a Whiskey Barrel Pond: Bird-Proofing and Debris Control

Compact Filter Options

Most external filters are for larger ponds. The Aqua-Mart Bio-Pond Filter (compact, no UV) at $33.95 (item FMF1) or the identical Drs. Foster & Smith GX-480563 at $29.99 are the smallest affordable units. They require a separate pump and tubing.

Alternative: Second Barrel as Filter

Plumb a second whiskey barrel (with liner) as a settlement/biofilter chamber. Water flows from main barrel to filter barrel, then returns via pump. Cheap and effective.

Bird Deterrents

Cover the pond with netting or a grid of fishing line to discourage bathing birds.
