Courtesy of a pond expansion last fall, I have a preformed liner (about 100
gallons) that I'm thinking about using as a lily pond. I can put in direct
sun and make it look nice.

The lilies didn't do well in my pond since I think they didn't get enough
sun--still won't if I put them back in the main pond.

My question is if I establish a lily pond do I need filtration? I wouldn't
put fish in it but am concerned about stagnant water.

Any advice would be appreciated.
