The SpaGuard series of products are good and easy to use. The Calcium Hardness increaser is no exception. Turn spa on, dump it in, and it raises the hardness in your water. Easy peasy.In my experience, the problem comes if you've decided to use the SpaSentry product to help keep your pH steady for longer. An effect of using it is that it removes calcium from your water. So it actually reduces the hardness in your water. Well, if you follow the directions on the Calcium Hardness increaser, when the hardness reading is below 150ppm, you add the increaser. Which the Spa Sentry product, already in your water, precipitates out (as those white clumps you see in water). This fills your filter which then must be cleaned. And it drops the hardness again. Endless cycle...This product does what it's supposed to well. Its the SpaSentry that causes the problem. Your mileage may vary, but I'm staying away from the SpaSentry product next refill and manage pH the old-fashioned way of using pH increaser/decreaser as needed.

This is a great product. I have been using it for years and it's a good price. We recently purchased several items of the same brand (not this one) so we are going to try to use one brand for all chemicals - so we will see how that works. If not, I'll definitely go back to this one.

Works just as it's supposed to
