Be careful.  Shouldn't be a problem with the water tank I imagine,
although I'd want to see some literature on effectiveness.  But we
put some (oxygen bleach) into a boat holding tank once, and the tank
started swelling and blowing dirty foam out the vents in the bow.  We
got the 1 1/2" discharge valve open before anything drastic happened.
