How to Enlarge a Koi Pond
As a novice Koi pond keeper, it's easy to make plenty of mistakes. Luckily, fish and plants are forgiving. One big mistake is in not allowing enough room for tiny friends (who aren't so tiny any more) to grow and thrive. After a while, you may realize that you've just got to have a bigger pond.
