Is dry acid reusable once wet

[another goof]

New to tfp so I do not know where to post this.. Regarding dry acid: by mistake I dumped way too much dry acid into a bucket containing pool water. I quickly poured the water into the pool, leaving several wet pounds of the acid in the bucket. Now I am wondering what to do with the wet acid. If it dries can I use it?

I would dilute heavily and put it down the drain. Use muriatic acid to lower pH

Dry acid add sulfates which attacks concrete and metal. No Bueno for El Poolo...
