Just wondering why folks build their swimming ponds with down flow bog, and fish pond with up flow bog.
What's the difference in how they work as to bio filtration. Or is it just two different ways to skin the same cat?
When I built the swimmin' pond I used an up flow bog, just like i have at the goldfish pond. It works very well.
