Pro-Kleen 251646 ScaleStop Hot Tub & Spa Descaler 5L-Limescale Removal & Prevention Inhibitor, Multi

Excellent product and price, works really well

This will last ages with the stated usage needs. 100ml initial dose then 30ml per week. I never used a descaler in the tub but my heater element clogged up needing to then be replaced. This will now keep that at bay or reduce the buildup rate to a minimum.

I recently tried the Pro-Kleen Hot Tub & Spa ScaleStop for my spa, and I was impressed with the immediate foaming action as soon as I poured it in. It wasn't just the effectiveness that caught my attention; the clean and pleasant smell it left behind was a refreshing change from the usual chemical odours one might expect from such products. The ease of use is a big plus—no complicated measuring or mixing is required. The clear instructions made it a breeze to administer the initial dose (100 ml per 1,000 litres of water), and the weekly maintenance dose (30 ml per 1,000 litres) seems straightforward enough to keep up with. Although I have not observed a significant reduction in scale build-up as of yet, I remain hopeful. The product seems promising, and I believe a bit more time is needed to see full results. All in all, the Pro-Kleen Hot Tub & Spa ScaleStop has made hot tub maintenance much simpler and more pleasant. I'll keep using it and would recommend it to others looking to keep their spa water clean and scale-free. Time will indeed tell, but for now, I'm giving it a solid four stars!

Wow! I am one happy customer! My tub was tripping out every couple of days. Since using this product it had only tripped out once...and that was due to a power cut. Alk the limescale has gone and my hottub is running like a dream. Follow up...I have continued to use this product on a weekly basis for the last 3-4 weeks. My hot tub has run perfectly since. It no longer trips out daily and I use less filters too. Definitely worth the small investment for a lot less hassle and increased filter life.
