Pond Boss Forums AERATION Systems questions New Pond - Windmill Recommendation

Here are just a couple suggestions.
1. Make sure there is good exposure to the wind from at least 3 directions. Catching prevailing wind is very important. A windmill is very poor if it doesn't catch wind from at least 3 ways. I've seen people put up windmills that have trees nearby on one or two sides - poor decisions and planning. A 1/2 acre L shaped pond will be hard to circulate and mix with just one diffuser. It is very difficult for the aerator currents to mix both embayments with just one diffuser. Windmills typically operate one diffuser.

2. The circulation in an L shaped pond will be much better if it is performed with 2 diffusers operated using electric 1/4-1/3 hp compressor. For self installation and same airline and diffuser an electric aerator system will be cheaper than a windmill. A 1/2 acre new pond in WI will not need the aerator operated 24/7. Six - 8 hours a day should be adequate. Lots of 1/2 acre ponds in NW OH are well mixed with 5-6 hrs operation.

3. Expect to pay $600-$800 for a good electric bottom aerator - this is less than the $1200-$1,500 for windmills.
