I would anchor your boxes better.. Cool Idea. But I think you'll be surprised by the bouyancy. Also I'd make a vent in them so trapped air can escape, I thought I read on here the trapped air can become toxic, (if actually close to airtight) don't quote me on that.. Cool looking pond thanks for bringing us along for the ride..

PS- while she's low I'd put in my posts for Pier/dock.. It'll save you alot of headache..
