Beware the underwater domino effect
Wire could work as well - just don't do a shoddy job of anchoring it lest it rise up all of a sudden and crack a canopy, light and/or cross-brace.
Must encourage all to leave off with the bleach - basin/tub of hot water, mild soap and possibly a wire brush is plenty. Bleach should be reserved solely for those rare instances where the use of a flamethrower or napalm is inconvenient and/or when one is dealing with a Marburg-level outbreak, which is to say, almost never.
