Compact 30cm Elite Bakki Shower | 3-Tier Koi Pond Trickle Filter
Achieve superior biological filtration and exceptional water clarity even in smaller setups with the Elite 30cm Bakki Shower. Handcrafted for maximum performance without the premium price tag, this compact 3-tier trickle filter simulates nature’s own purification process—replicating the highly oxygenated environment of a mountain stream to keep your koi pond water pristine.
Key Features for Premium Filtration
High-Efficiency 12mm Mesh Bottoms: Unlike standard filters with simple drilled holes, our oversized tiers feature heavy-duty 12mm mesh bases. This design massively increases structural strength while ensuring an aggressive, unhindered water cascade for superior aeration.
Optimized Water Distribution: Includes a pre-drilled 1.5” spray bar designed to deliver a perfectly even spread of water across your filter media. (The pipe can be easily drilled further to accommodate custom flow setups).
Pre-Formed Weir Return: The built-in weir guarantees a smooth, waterfall-like return flow directly back into your pond system.
Handcrafted Durability: Built to withstand heavy use, every joint is meticulously hand-welded. (Note: As a bespoke handmade product, slight visual differences in the welds are a natural hallmark of its robust construction).
Plug-and-Play Installation: Delivered fully built and ready to run straight out of the box.
How the Trickle Filter Works As your pond pump pushes water into the top spray bar, the water crashes down through the three tiers. This continuous smashing action rapidly drives off harmful carbon dioxide while aggressively saturating the water with oxygen. This creates the ultimate highly aerated environment for beneficial bacteria to thrive, consume harmful ammonia, and process nitrites.

We make it simple: we sell our media in pre-measured "Tier Packs". One pack fills one tray perfectly.
Which media is best?
We recommend a variable pump running at 10,000 - 15,000 LPH max on our showers you can then adjust speed to suit head height etc. Our showers work well from any flow above 3500lph.

"Great filter. Perfect addition to my small pond. Very pleased."

"Excellent buy for small grow on ponds. I have two of my koi grown on pond. They do a fantastic job. I put filter floss under the spray bar in the top section the waste it removes from your pond is amazing. I have filled each section with different filter media. A great buy for smaller ponds"

"Very pleased with design. Despite relatively small size still able to get decent quantity of media in each section and still leave room for water to drop from each tier and splash inside. Also purchased 200 micron filter tray to go under lowest section. Surprised by how much this is removing from water. Too early yet for bacteria to become active but koi spending time swimming under waterfall."

"Excellent extra filtration for small grow on pond. Put a piece of filter wool under the spray bar to catch fines. Want to purchase another section to make it 4 tier."

"Had this running since September 2024. I have it connected to my skimmer and am roughly putting 2000lph through it which is more than enough for my size pond. It is small and compact and is perfect for the smaller pond owners. If you opt for the media package it will be supplied prefilled with alfagrog. Sadly, the way the item arrived and is packaged is probably my only moan about this item. The filter is prestacked and was then wrapped in 3 different flattened out boxes that had been taped together to make fit and was wet in areas which had then become mush, this was from the alfagrog that is supplied unbagged and free floating in the shower sections, it's soaking wet and was everywhere when the package was opened with some reduced to tiny unusable pieces. I honestly thought the trays would be damaged, but after inspection I found they are fine which shows how good the build quality is."

"Very happy with it looks good and seems to have made the pond water much better"
— Paul O. (5/5)
"Only been on pond for 7 days already the difference is notable only floor is the hole on blank side is a fraction too large and a element of water does slash through not too much of a concern will look into ways of sealing around it. All in all an excellent product"
