Bead Filter vs Pressurized Pond Filter: Which for Koi?
Bead filter vs pressurized pond filter compared: biological capacity, backwashing, koi stocking, running cost and which suits your pond.
The short version
A bead filter holds an enormous biological surface area and backwashes without being opened, which is what a koi pond needs because koi are heavy waste producers. A pressurized canister with a built-in UV is cheaper and simpler, and suits water gardens and lightly stocked ponds. Buy the bead filter for real koi stocking; buy the pressurized filter for a garden pond with a few fish.

Choose the EasyPro PBF1800 Bead Filter if…
You are keeping koi properly rather than a few goldfish. Koi produce far more waste per fish than most people expect, and biological capacity is what keeps ammonia at zero. A bead filter also backwashes in a couple of minutes without opening anything, which matters when the alternative is a messy weekly job.

Choose the TotalPond Filter with UV Clarifier if…
You have a water garden, a handful of small fish and plants doing much of the work. The built-in UV clarifier deals with green water, which is usually the actual complaint people have about garden ponds, and it costs a fraction of a bead system.

Frequently Asked Questions
How much filtration do koi actually need?
Far more than the pond volume alone suggests, because the load comes from fish mass and feeding rather than gallons. Our pond filter sizing calculator works from stocking and feeding rather than volume alone, which is where most undersized systems go wrong.
What is backwashing and why does it matter?
Reversing the flow to flush trapped solids out to waste without opening the filter. It matters because a filter that is annoying to clean gets cleaned less often, and a clogged filter loses both flow and biological function.
Do I still need a skimmer?
Almost always, yes. Filters deal with what reaches them; a skimmer stops leaves and pollen from sinking and decomposing in the first place, which is far easier than processing them afterwards.
