3,500 gal water garden with bog filter


Estimated 3,500 gallon water garden. I have a 13'X5' upflow bog filter that waterfalls back into the pond. The bog provides all of the filtration for this pond. A 4,100 gph submersible pump provides the flow to the bog.

Still working on it. This is what it looks like as of 4-18-2019

Planning and Construction

I have Purple Martins and they are her from March to July. My Martin house was right were I wanted my bog plus I didn't want to disturb them with all of the construction. So, I had to wait until the off season to do this project. I started construction in the fall of 2018.

Started out by laying out a water hose to get the outline of the pond. The Pond Digger YouTube series was my major inspiration for how I wanted to build my pond. Addy's bog construction thread in this forum was my major inspiration for how to build my bog.

It took about 2 weeks (working here and there on my days off) to hand dig this pond with hand tools and a wheelbarrow to haul the approx. 18 tons of excavated dirt out back.

I didn't work much on the pond over the winter. I've still got a lot of finish work to do, but I finally got the bog finished enough in April 2019 so that I can turn on the pump.

Fish / Plant Stock

I plan to stock the bog with tons of plants. I will also put plants directly in my pond. I built planting shelves in my pond with plant pockets. Lilies will be in pots in the deeper water. I also plan on putting plants in the nooks and crannies of the coping stones.

I will eventually have koi in my pond. I put some Rosy Red Minnows and Mosquito Minnows in to start cycling the pond and to help with mosquito control.
