I feel silly asking this, but here goes.

Today I wanted to raise my borate level a bit (I use tetraborate pentahydrate). It was a bit windy, so instead of broadcasting it per label instructions and having it blow around, I thought I would put it in a bucket and add pool water to pre dissolve it then pour it throughout the pool.

Well, some of it dissolved, but most of it solidified into a big borate rock! Is there a way to dissolve this "borate rock" so I can use it, or is it toast?
