I seem to remember reading somewhere that bleach can be bad for some

seem like 10% would be that bad.

What is the best thing to "flush" your system with to clean it out?

Clean fresh water is all you need 90% of the time. At the end of the
season, clean fresh water and detergent.Wisk is best, but any laundry
detergent that doesn't contain bleach is ok...or Dawn or any of the
other dishwashing liquids. Avoid Oxiclean and similar products...they're
oxidizers, and oxidizers promote oxidation (rust, corrosion).
