Recently single parent and totally on my own so sorry if this is a silly question.
DC have a small water play pool thing. I’ve ignored it for months. It’s full of water and has been for a long time. It’s had rainfall in it but from a brief google it still constitutes standing water and can be dangerous.
Probably best to replace the thing anyway but how can I ensure it’s bacteria free before tipping all the water out? Is there a treatment I can use? I’ve looked on B and Q but feeling totally out of my depth (pardon the pun!). Any help massively appreciated
