@CarlaSee
I don't have a bog but wish I did. Ask questions as those who have bogs will be happy to help.

I'm a tad concerned that your "koi" pond is only 700 gallons... that's not much room for koi. How many fish do you have?

You'll never regret building a bog filter - we love ours!

something is off; doing the math, your pond is an average of 12" deep? Gallons = length x width x avg depth x 7.5. Maybe so but that's pretty shallow for just about any locale. And a good rule of thumb is 1000 gallons for one koi, 500 for additional. Koi can get 30+ inches, so...
