Take a look at our recent '
Pond Water Change Out'. On March 7, 2010, we did a complete pond water change out of our goldfish and Koi pond. This is the first complete water change out and cleaning since the creation of the pond around 1994. That's a lot of years without having to change the water! That means we got it right. Specifically, for a pond to survive, live, and grow, with very little maintenance, you have to find that perfect 'natural' balance. The change out of the pond water caused a minimal loss of fish. Of the 106 fish, we only lost 13 in this radical pond environment change.
