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.

Mint fileration system, how did you do the 5 uv lights

[hooinc]

What do you mean?

[alij08]

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

[hooinc]

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

I LOVE THIS POND!

YOUR FILTER SYSTEM IS MY KIND OF SYSTEM!

Very technical and intricate.

Very nice!

Best Regards,

Erik

Thanks, Erik. There is a separate bakki shower circuit for my pond. This video only shows the mechanical/biological filter.

The filter has 4 chambers and is backflushed twice a day. It is emptied out every 2 weeks and filter materials washed. Each chamber has a bottom drain.
