Bakki Showers. What do you know and are they a good way to filter the water? -Cam

Nitrifying bacteria in ponds need three things to thrive:
  1. Water
  2. Food (Fish Waste - supplied by your Koi)
  3. Oxygen
A Bakki Shower is a wet/dry filter.

A Bakki Shower is basically a bunch of boxes (chambers) with perforated bottoms that are stacked ontop of eachother and then filled with filter media. Water that is taken from the pond is pumped up into the top chamber, where it then proceeds to fall down through the rest of the chambers and then back into the pond. When the water falls and hits the filter media, the nitrifying bacteria that live on it do their thing by converting the toxins that Koi produce into Nitrate. Also, the water hitting the filter material creates a large amount of agitation, making it absorbs a lot of oxygen, which both Koi and Nitrifying bacteria need.

The Bakki Shower will filter your water and aerate your pond at the same time.

There are a few of downfalls for this type of filter:
  • A Bakki Shower provides no mechanical filtration.
  • A single Bakki Shower is only good for a small to medium sized pond. A large pond will require several Bakki Showers, which will increase the overall price of a pond and the overall noise level.
  • A Bakki Shower will create some noise. If you prefer you water feature to be peaceful and quiet, this may not be a good choice for you.
Bakki Showers are good for filtering a pond. They are relatively easy to install and easy to maintain.
