I would not put any plant in bleach; Rhonda Wilson once wrote that the risk exists for any plant and it is not wise. Any substance strong enough to deal with snails, algae or pests on any plant is almost certain to harm the plant in some manner.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
