I still have a bit of rock work to do, but it is coming along nicely. I am in hopes that someone looking to place some culls might consider my 7500 gallon pond. It is 4' deep at the deepest, has two falls (not in operation a time of photo) producing a 1 hour water turn over rate and a 600 gallon bio filter. Approximated size is 32' by 21'. I used the Firestone EPDM Liner and installed a bottom pick up line and a top skimmer. I will be adding lights soon.
