GLB71410A Natural Clear Enzyme Clarifier, 32-Ounce

Makes our hot tub extra clear. I had tried another brand of hot tub enzymes but they were very expensive so we tried it without for a few months and had more issues with scum on the water and it just wasn't as clear. We purchased this and now our water stays very clear. We maintain a low chlorine level and use potassium shock and add about a 1/2 cap of this a week and the water is beautiful and smells good.UPDATE: I wanted to update this review since I realized one bottle of this lasted us an entire year at 1/2 cap a week. We have had fewer water changes in the past year and we do not get that scum line or any foam like we used to. This is the biggest money saver and keeps our spa beautiful.

GLB Water Clarifier is the best enzyme cleaner I have ever used in my spa! The past enzyme cleaners were okay, but didn't really remove oils and lotions that were inadvertently taken into the spa. GLB does...beyond belief. All "scum" problems have totally disappeared. In addition, the owners of Razor Sharp Products are the best! When I had a customer service problem, it was handled quickly and professionally. Great product from a Great company!

Had a small spill of hydraulic fluid in our pool, made the water completely gross, cloudy and shiny on top. Poured this bottle in and within a couple hours the water was crystal clear, all the contaminants were lying on the bottom to be easily vavuumed up.
