Title: Great
Review: We only have the 12ftX3ft pool, so we needed to upgrade our filter to use it. But, it has been well worth it. We never have to buy expensive, dangerous, toxic chemicals again. I check the levels about once a week. If the levels are too high or low, I just adjust the run time. It's fabulous! For a pool our size it's only about 1 hour/ day.
