I'm not sure how to do that yet. Maybe Ben is the only one who has access.

Some success was had. The new nut which replaced the cracked nut corrected part of the leak; however it was not the main leak. The main leak is coming from the filter where the gasket meets the metal of the filter. It is old and not very pliable anymore. Going to try a few things today, and if need be, go the jb weld route which I think/hope will fix it if we get to that point.

I'm thinking next year I'm just going to get a new D.E. filter, with a step up in size. The pool plumbing supply store charged 9 dollars for that plastic nut, ridiculous! Do newer filters come plumbed with standard PVC pieces/threading?

As far as the pool's daily chlorine fluctuations, at night I've been bumping it up to about 5.5 ppm. When tested the next evening, its at 2.5 ppm, so it almost holds at the minimum level but not quite. Should I bump up the CYA?
