My 300 gallon acrylic tank

I think this just happened in the last 2 to 3 weeks since it snowed.He couldn't hang the clothes outside so he strained them or left them in my bucket.I think he was washing them in there I don't know.The guy doesn't have a clue as to what is involved with the tank.When I told him he said he would wash out the bucket but he doesn't understand.I didn't bother trying to explain it to him plus I don't know what or if he caused any damage to the tank since my other fish are fine.I was just upset because I asked my wife to tell him not to touch my stuff.He probably didn't realize he was doing anything wrong.Anyways they are both weird and not very bright so what can I do.I can't say much and if I explode it won't be a nice thing to do to them.I let it be.I usually have a bad temper but I controlled myself.Better not to go off on him for something he had no clue about.
