I don't know if this is a dumb question, but here goes. I've done a few ponds, and used the aquascape system for most of them, but instead of sealing your liner into the faceplate of the skimmer or water fall box for that matter, why can't you just run the liner under the box and up the back higher than the box itself? Seal all your flexible pipes into the back of the boxes but let them run up out of the water behind the boxes, and cover with rocks or berm? I all alleviates the problem of leaking seals on the liners. Will this work? Anybody done this?
