Review: Used another product originally and did not clear up water at all. Purchased and tried HTH Spa Clarifier. This product worked great. After first filtration cycle, there was a ring around the tub with much scum, assuming soaps and lotion in the water from suits and bodies. Wiped clean, changed filter and ran again. Same thing with ring around tub but water was very clear. Rinsed filter and ran one more time. Excellent results. Would recommend this product to make water crystal clear. Make sure to rinse filter or change out as noted above.
Review: It works as labelled
