if and when you start fertilizing, i like the southern excellence buckets ...1 bucket for a couple acre pond i think...my pond is 7.5 acres and i put out about 3 buckets per month during season. easy, clean, and if things go hay wire you can take it out. happened to me one time after several cloudy days, came home from work and my pond had a milk color to it. pulled the buckets out and drove my boat with a 25 hp motor on it around the pond to aerate it the best i could. did fine. i'm waiting on getting my aeration system/diffusers soon. good luck, i think you'll love this site...get the books you can purchase on this site, they are a greeaaattt help. plus, these guys on here are sharp...and willing to help us wanna be pondmeisters!!! have fun, keep us posted on your pond. mark williams
