Hi there, so I read a lot of these articles, and I settled on a HiBlow 120LL for my aeration rig. I read a couple posts where Journeyman had talked about using 3/4-in PEX out to a diffuser.

I bought the PEX and some 3/4-in fittings, but the PEX is way more rigid than I expected, and I'll be damned if I can push the barbed fittings into the pipe. It's cold out, so I brought the PEX in last night to warm up, but it's been inside for 24 hours now, and it still feels like I'm trying to push a barbed fitting into a piece of PVC. Is it supposed to be this rigid? Am I supposed to heat it before trying to push the fitting on?

THANKS!
