Elite Bakki Shower Trickle Filter 90cm Width 2 Tier | High-Efficiency Koi Pond Filter

If you are looking to dramatically improve your koi pond's water quality without sacrificing vertical space, the 90cm 2-Tier Bakki Shower delivers premium biological filtration in a streamlined footprint. Handcrafted for serious koi keepers, this dual-tier trickle filter provides exceptional oxygenation and off-gassing, proving that you don't need a massive, expensive tower to achieve pristine water parameters.

Core Design Features

  • High-Flow 12mm Mesh Grids: We've bypassed standard drilled holes in favor of heavy-duty 12mm mesh bases on both tiers. This design prevents media clogging, drastically increases structural integrity, and ensures a highly aggressive water sheer for maximum oxygen uptake.

  • Precision 1.5” Spray Bar: The included spray bar is pre-drilled to guarantee an even, wide-spread distribution of water over your chosen media. Should your specific pump setup require it, the pipe is easily adaptable for additional drilling.

  • Handcrafted Durability: Built to last, every single joint is meticulously hand-welded. This bespoke construction method results in unmatched strength (please note that slight visual variations in the welds are a natural hallmark of this handmade manufacturing process).

  • Custom Angled Spillway: The pre-formed weir features a slight tilt to the sides, enhancing the unit's overall stability while creating a smooth, waterfall-like return straight into your pond.

  • Generous Aeration Chambers: Despite its reduced height, both tiers remain oversized in depth and width. This allows massive amounts of air to interact with the crashing water, accelerating the nitrogen cycle.

The Trickle Filter Advantage This 2-tier system rapidly breaks down harmful ammonia and nitrites by exposing beneficial bacteria to highly oxygenated water. As water is pumped into the top spray bar, it smashes down through the media beds. This continuous crashing action drives off harmful gases like carbon dioxide and saturates the water with oxygen—creating an ideal biological environment for healthy, vibrant koi.

Frequently Asked Questions

What media do I need (and how much)?

We make it simple: we sell our media in pre-measured "Tier Packs". One pack fills one tray perfectly.

  • For a 2-Tier Shower: Add 2 packs to your basket.
  • For a 3-Tier Shower: Add 3 packs to your basket.

Which media is best?

  • 🥇 The Gold Standard: Far Infrared Bacteria Home
    This is the ultimate media for our showers. It is lightweight, incredibly porous, and offers massive surface area for bacteria. If you want maximum growth and glass-clear water, this is the "best of the best."
  • 💰 The Budget Choice: Alfagrog
    A solid, reliable alternative. It is heavier than Bacteria Home, but it offers great biological filtration at a lower price point.
  • Here Is Our Full Selection

Whats the max flow rate?

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.

How long is dispatch?

Due to high demand, our current manufacturing lead time is 7–10 working days before dispatch. We refuse to rush the welding process to ensure every unit meets our strict quality standards.

A Note on Tracking:
Once your unit is ready, you will receive a dispatch email. Please note that DPD tracking may not update immediately. It often takes 24–48 hours for the parcel to be collected from our Isle of Wight workshop and scanned at the mainland depot. Please be patient—if you have the email, it is on its way!

Can I order a custom size or specification?

Yes! Because we build everything in-house, we can modify the design to fit your specific setup.

Common Customizations:

  • Size: We can build custom widths up to a maximum of 120cm.
  • Inlets: We can upgrade the standard 1.5" inlet to 2" or 3".
  • Outlets: We can swap the standard weir for a piped outlet or fabricate a custom-length weir to match your waterfall width or length.
