Must have for great hottub water
Didn't use it yet, but I expect great results.
Great
The product was recommended ( works great
Works as suppose to. Easy to open the lid.. Read more how I take care of my water
Not sure why everyone is complaining about the lid. Just follow simple directions? I lifted the red pin and twisted off (counterclockwise) with ease. Closed it and did it again 2nd time for the video demonstration.. if you indeed have trouble, dont use crazy tools, just hole saw a hole on top or use box cutter knife and cut a triangle and dump it into a ziplock bag. What's the deal, I was gonna do that after reading all the reviews but it opened without hassle for me. Purchased in Dec. 2024Will update in case doesn't keep the water clear, but I already have pretty clean water. Just little bit of chlorine and oxidizer or this stuff before or after each use.I usually add my stuff before going in, turn jets on to high to circulate for 15-20mins (sometimes 30mins) before entering, with lid open. So that After we're done, I don't have to wait with lid open and come out to it again. Just close the lid and go to sleep and till text time - repeat.Had my tub fot 3 months now, use it 3-6 times a week, water is clear and clean. Usually gets a little musty smell (like just a little) if not used for a few days (due to sitting and boiling under cover this whole time, without fresh air), but it gets taken care of before we enter every time.I usually just cover the bottom of the cap and eyeball it. Since I add it so often, I don't use suggested amount but way less... if I had to guess, it would be half-to-one ounce of product. If I do that couple times a week, that is more than suggested per week, but definitely not per each time I enter the hot tub. I have 8 person 550gallon hot tub, for reference.Please thumbs up my review if it helps!
