replacing a 12 year old DE filter

[optimator]

I used zeosand in that one, even adding a bag w/o improvement. I think my pump was too big and the filter too small for the pool and plumbing.

I ended up ordering a cartridge filter, finding one at a good price. This will eliminate my DE going into my neighbor's yard.

I hate to say you're wrong but I have a hard time believing a 300# sand filter was too small for a 1hp pump! I run a 1hp 2speed Superpump with a 200# sand filter and have for 11 seasons now with no problem. I suspect it was plumbed and set up incorrectly for the problems you describe to have happened. A 300# sand filter is definitely overkill for a 1hp pump (and it's OK to do that).

That would explain the crack in the filter body. Too much pressure coming into the filter.
