Sorry to hear about what happened, horrible. I read it on another thread.
You should be able to, lots of seachem safe/prime....or even drying it out completely should work
ThisI agree that a lot of people here have said they used bleach to clean certain decor or items then after a good rinsing, they soak said item in water with an overdose of prime for a day or two, then soaked in plain freshwater for another 24hrs to be safe...
I would also test the pool with some cheap dither fish before re-stocking properly to avoid any costly losses...

This is exactly what I do all the time.
Its going to be a total PITA to fill and empty that pool, but it'll definitely make it fish safe again.
I would recommend using at least 3X the Safe instructed dose and let it sit, fully filled with all the filtration running, for at least a week.
Remember, bleach is essentially chlorine from our standpoint with aquariums (might actually be chlorine).
When my son's tank had a heater issue that killed all of the fish, I took everything over to the sink and soaked it in bleach water...including the filters and media.
