Yes, but it usually takes a lot more dry acid than muriatic to get the job done.
You might be surprised how much time your kids spend playing in the fountain. We have a slide in our pool, but the kids spend much less time actually sliding than they do playing in the runoff from the slide!

Thanks guys. I'm off the test again.
True about the fountain! The kids can't get enough. I want to get a slide next year, but they're so expensive.
Take care,
Bill
