New build basics – 3750gal free-form, RDF and moving bed bio-filter gravity fed, UV sterilization, two aerated BD’s, one skimmer, two TPR’s, waterfall, turnover once per hour (or better), 4ft depth at sloped bottom, straight sides, two plant shelves, cinder block wall construction with EDPM liner, 2.5’ below grade and 1.5’ above grade.
It's happening! I got a hole in my yard, so I guess I'm committed.
Next is putting down 1st layer of block, drilling into grade beam and expoxy'ing in vertical rebar (doing this after placing the first row of block as the pond is free form and it would be hard to place rebar in advance).
After that, placing BD's and running 4" to them from around the corner of the house. Still looking for suggestions on brand of BD (aerated) if you have opinions! This, or finish another three layers of block. Order not critical at this point.
