We've had our pond for almost 8 yrs. It's app. 600 gal. and in our backyard close to our bedroom window. We live in N. Fla. Right now it's covered with netting as we have tons of leaves that are falling. We had a sprinkling of snow last week with highs in the 70s this week. The hostas that are submergibles have frozen. Mid-Feb. i s the time to begin this year's pond.
