its not trusted for use indoors but it is submerged with fish
that rope idea is really good! i bet it would work. its just getting the rope in the write place while a growing lake builds up behind it
the concept behind the dog ear is is that water will get into the creased flap on the outside part of the liner and equalize water pressure which will then squeeze the air out of the inner fold, that doesn't look like its there but is, leaving you with a flap that is going to want to stick into the water column. to solve this, make your folds like so then seal the corners, this will keep the liner flat. just make sure to get the liner perfectly fitted cause if you don't and you seal the corners, the seal will be broken when you fill the thing.
i really think that trying to position the rope and folds and everything is going to be a reall pain in the arss. going with the red cross will be easier i think, but atleast with the folds if you can't do it you can always go to the red cross, but you can't revert from the red cross back to the folds
i just learned about a new application for a cool thing on necro's 18000 gal build. its called a flow accerator and increases you pumps flow rate by a ton. it would def come in handy on this beast!
good luck! excited for this thing to start taking shape! will you start a new thread when the build prgresses?
