pH with breeding bronze cories

I have 3 bronze and 3 albino aeneus cory cats. Does pH affect breeding, if I want to set them up to spawn? They've been in hard water all their life....and would bristlenose plecos eat all the cory eggs?

Both.
You can safely bet on any fish trying to eat the egs; Ancistrus among them. They're nicely glued to the glass and the plants so any Loricariid will have an easy meal. The Cory's themselves will try it too; at least the ones that aren't spawning or laying at the time.
And a high pH isn't optimal, although Bronze Cory's are very tolerant. But setting it at least to neutral will help, getting it lowered to 6 or so even more (they don't need a very low pH; 65 - 7,5 will do fine) and will decrease the chance of fungus. (fungus or bacteria grow a lot slower in water with pH lower than 7.)
Be advised that pH is logaritmic, so water that has a pH 6 is 100x (!) more acidic than water with pH 8......so you'd better go slow when messing with the pH.
