Every spa owner should buy these
I am one that reads reviews all the time, but am terrible at posting them either good or bad. This product however deserves press. We don't use our tub nearly as often as we used to. When we would get the urge, we had usually been too busy or lazy to keep it up. That would then start the process of a major shock, then maybe get in the next day. This little doo dad allows us to check our tub about once a week, add a touch of chlorine and in business. One caution, it will throw off your water testing results. Ours will always show Alkalinity low, PH high and chlorine low. We talked to local spa dealer who claims to us that with this product, don't worry about it.
