Elite Bakki Shower Extra Tiers | Modular Koi Pond Filter Upgrade
Expand your pond's biological capacity effortlessly with our Elite Bakki Shower Extra Tiers. As your koi grow or your stocking density increases, your filtration needs will evolve. These modular extension tiers allow you to instantly scale up your existing setup and supercharge your water quality without the expense of buying an entirely new filter system.
Key Features for Easy Expansion
Seamless Direct Fit: Designed to integrate perfectly with your current setup. Simply select the exact width of your existing Elite Bakki Shower, and this extra tier will stack securely right on top.
Boosted Biological Filtration: Adding another tier instantly increases your media volume and extends the water's contact time with beneficial bacteria, leading to faster ammonia and nitrite processing.
Heavy-Duty Handcrafted Build: Just like our complete shower systems, every extension tier is meticulously hand-welded for robust, long-lasting structural strength. (Please note: As a bespoke, handmade product, slight visual variations in the welds are a natural characteristic of the manufacturing process and do not affect performance).
Cost-Effective Upgrade: Maximize your pond's aeration and purification potential without breaking the bank.
Important Product Notes To keep shipping costs as low as possible for our customers, these extra tiers are supplied without filter media. They arrive ready to be instantly filled with your biological media of choice, whether you prefer Alfagrog, pumice, ceramic rock, or bacteria home media. All available HERE

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.

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

We don't import cheap plastic shells. Every Apex Koi shower is hand-welded from chemically resistant, UV-stable polypropylene. They are designed to withstand freezing UK winters and scorching summers without becoming brittle.
Buy with total peace of mind. Because we build them, we back them. Every shower comes with a 1-Year Manufacturer’s Warranty on faults. No call centers, no runarounds—just direct support from our workshop team who know your filter inside out.
