kickboxing bag

I just bought a new standing kickboxing bag…the kind where you fill the plastic base with water. My question is, should I put something (like a little bleach) in with the water to keep mold or anything from growing in there?

yep. i don’t recall anything ever growing in ours but the water smelled a little “funny” when we would uncap the thing. so i guess it couldn’t hurt to add a little bleach.
