    Technically yes. However if you don't have a D.E. filter you'll need to use some kind of filter aid to help get more of the calcium to filter out.

    Unfortunately, it doesn't work well with sand. You can try adding either fiberous cellulose filter aide or a little D.E. and the Cal Treat might help lower the calcium, but likely it will only be a small amount. Sorry.

    No it shouldn't have any negative impact on your equipment.
