Can anyone tell me if I have enough space between my pool chemicals in the deck box and these metal things on the back of the shed (see pic)? Inside the deck box is powder shock, chlorine tablets and bags of stabilizer. The shock and tablets are in their original buckets and the buckets are in the deck box. (No muriatic acid - that I knew!) Just want to make sure any fumes wouldn’t hurt the metal stuff on the back of the shed. Thank you! Here are the pics:
