I bought a house with a 1 acre pond last summer about this time. It's an old farm pond which now has had sub divisions built all around. The pond had nearly 100% coverage of FA when I bought it...last year I installed 3 bottom diffusers and this year added a Kasko Surface Aerator. I've been using bacteria and three "pond logs"

The bottom line, do a ton of homework as to what will be best for your issues, if you even have any and remember, before aeration became the "in thing" many lakes/ponds lived for years and years without a problem. After spending well over $5000 on this pond in a year and not seeing any results...am I ticked off ? You bet !
