Yes the HC lasts longer, and you can flow more through it, I change mine every 3 weeks to be safe because without a reliable test kit for po4 it's hard to say how long for sure, I regenerate it about 10 times before it gets too fine to use anymore.

This is the link, I skip the acid wash and use a Rio 400 pump cuz the maxijets don't last, I use lye crystals from Home Hardware.
