Bakki Shower

I have questions regarding bakki showers. As I understand them you pump water directly from your pond drains into the top tier of a bakki shower and gravity takes care of everything else. Am I correct in understanding that you do not use any other filtration system with a bakki shower and that it alone accomplishes your filtration needs? What happens to the solids that are filtered out of the pond? Are they trapped in the bakki showers? If solids are trapped in the bakki system do they have to be periodically emptied and cleaned? What kind of ongoing maintenance does a bakki shower system require.

Thanks for you help with my questions.


You need to have some sort of mechanical filtration before the bakki shower in order to remove the majority of solids. If you don't, the bakki shower will clog often and it will require much more maintenance. The bakki shower does provide a great amount of biological filtration. If you have mechanical filtration before it, the only maintenace is a good cleaning of the filter material once every couple months.

Algae Problem

I have Koi in my pool, about nine of them in 14,000 gallons of water. I have been using the pool to filter the water, but I am having trouble ridding the pool/pond of algae. Any ideas? -Chele

It depends on what type of algae you are having problems with. The type that makes the water itself green can be treated with a couple of powerful UV lights, like these: http://www.koiacres.com/Koi-Acres-Products/ultra-violet/high-output-uv.html.

If you are having problems with string algae, you can either add chemicals to remove it (which can be costly) or you can remove it by hand.

Koi In A Swimming Pool

Hello,
I would like to have Koi in my swimming pool. Is the pool too deep? I will keep the water pH right. I am in southern Mississippi and the water gets warm.
If I do get Koi for my pool can we still swim, can they live on the algae generated or do I have to feed them, this seems like a green idea. What are your thoughts?

Regards,
David

First, before you put any fish in, make sure that any traces of Chlorine are out of the water. Chlorine will burn their gills. You will need a filter for the fish, regular pool filters are inadequate since they are filled with sand and will provide no chemical filtration whatsoever (ammonia will build up in the water and will hurt you fish).

The Koi can feed off of algae somewhat, but you should give them Koi food on a regular basis so they get the protien, vitamins and minerals that they need.

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.
