I use rocks from the yard and woods with no problems at all. Just don't use
porous rocks from agricultural areas where toxic sprays or spills could have
occurred. Shale is not porous so should be safe. No need to spend a bundle
at the pet shop for rocks.
HOWEVER - if these

Bleach wouldn't stop minerals from leeching from a rock that leeches.
Bleach (the chlorine in it) is only a disinfectant. It kills bacteria and
viruses.

Then skip the horrid red, blue and other unnatural looking gravels. Stick to
natural colors.

If you plan to keep fish that do better in acid or neutral water skip the
limestone rocks.
