yeah i went straight to the liner pond so when i do upgrade its going to have to be huge.....
I used to build in ground vinyl liner swimming pools, back when we had no ponds or aquariums, and I had a customer who had a unique idea for makin' some extra coin off of her family farm.
She started by raising talapia in aquariums, then moved to an old concrete pool that they hadn't used in years. Eventually she tired of having to deal w/ the talapia's short growth cycle (had to harvest by winter) and moved on to hybrid striped bass.
Now days they have corporate picnics and family reunions on the farm and basically cater. The main menu item is of course...striped bass. She had me build three more 28'x54'x6' swimming pools for her and that's what she danced with. Filtered with double sand filters, biological sump, hi vol. UV and ran big time air. Now they harvest at the end of a two year cycle and she's toyin' w' puttin' in solar hydronics, insulation and a poly house cover to fatten 'em up quicker.
Sorry, don't know if this skip OT is like lauding Hitler on a Holocaust site but I thought it was interesting nonetheless.
If you're as afflicted as I, skip the ponds, time to start diggin' pool holes.
