I would if the pool looked green, which it doesn't.
I think it's overkill, the pole brush does a great job imo.
PLUS we have a really efficient pool sweeper running around the bottom 2 hours a day.
The gear is the shops btw.
So this means your dad just wants to play in the pool. If you are really worried about him doing it, then You clean the already clean pool, and he will have no excuse, however imagined it is.
The shop's gear. They shouldn't be giving a student gear and a tank to go, without him already having finished class and all pool sessions. And Then, only if they have to drive to a quarry or shore for OW dives the next day. I think this was a really bad idea on their part. It's like giving a little kid fireworks and the lighter and saying, Just hang onto these until a few nights from now and I'll show you how to set them off." Just begging for trouble.
Tell him, Jim!
