We'll have a lot of room. We're changing out our built-in pool (which will take some time all by itself) that doesn't get used too often any more now that we're empty nesters. We pay to swim in it for 3 or 4 months of the year and pay to keep it clean the other 8 or 9 months when it doesn't get used. The electricity for a pond pump has got to be less than a filter pump and a sweeper pump. Water usage will be less too. No cannonballs and water fights splashing gallons of water onto the deck and down the drain.
