We have an 80,000 gallon Koi pond. It has never been filtered and the water is green.

I have a mud bottom natural pond about 28,000 gallons and a big fountain. Will a bog help clear my muddy green water? I have 7- 2ft. koi and about 30 4-6in koi. I feed them 1/2 cup per day. Where can I find instructions for building a bog?

Addy1 is the queen of bogs! She is the one that inspired me and many others. She has an extensive thread on the process. I just can't seem to find it. Maybe someone can help find it and post the link here.

Here's the bog I recently added to my pond:

Oh goodness, I know a lot about backyard pond bogs but nothing about “natural bogs.” In general, yes, a bog will help with water quality, but the kind of bogs we have are self-contained and plumbed as part of a lined pond. Any time you add plants, it’s a good thing.

Thank you for your help. I didn't intend to be a pond person but I couldn't stand to see the fish get thrown away and AA county made me dig the hole anyway. Everyone is just amazed that I do nothing for water quality except aerate and the fish are quite healthy anyway.
