I have a 5.25 acre pond that I just drained and had it mucked out and taken back down to clay (where there was clay). We only use the pond for swimming. We could not find any natural springs when we had the pond drained but I did just have a 5 hp deep well put down to help keep the level up. Before we drained it, in the summer the water seemed stagnant and would leave a brown film on your skin when you got in. Would an Airmax help with the film that gets on you? I'm kind of leaning toward the Airmax system but I'm not sure if that's what I need. Like I said we are only interested in swimming and would like the water to be a nice color. In the past it was mostly a dark color that was hard to see through unless the sun was shining straight down. It has a channel dug the length of it down the middle and is probaly 20' in its deepest point. Thanks for any help![img]https://ibb.co/4VSgtVB[/img]
