V8 27/10/08 My Biofilter

NOTE - THIS VIDEO HAS BEEN SUPERCEDED BY V44 which you can view at http://www.youtube.com/watch?v=TVI5a9UYILQ

My koi pond mechanical/biological filter just before washing. My filter is only about 20% of the total pond+filter volume of 80 tons, but I have an independent bakki shower filtration circuit (see also V23). Moreover, I have only 15 koi in my pond.

Check my channel http://www.youtube.com/user/hooinc for more koi videos.

LOL, but why do you have a waste water treatment in your home?

It's the biofilter for my Japanese koi pond.

Hi.... great filter.... though I suspect you need it for all those large koi !

Can I ask .... does the crushed oyster shell do a good job of buffering the hardness and ph ?..... what is your local water like before use ??

[hooinc]

Hi Sandy, the crushed corals were ok as a buffer, but very difficult to clean. Oyster shells are much easier to clean. Local water has Ph of about 9.0.

O, i see, kool idea (Y)

[hooinc]

They are submerged UV lights, designed for use IN the water.

[alij08]

Like... how are they underwater?, because most of the time you see the uv lights in sealed units

[hooinc]

What do you mean?
