Product Awesome...Lid Not so much
This product works as advertised and has been EXTREMELY effective in keeping our water clear. Complaints about the lid on the container are real. It is extremely difficult to open and I don't see any reason for such a complex lid design...the company must have gotten sold on this design from a family member or someone they owed a favor because no sane person would think its easy to open or use. But it's worth the headache for how the treatment works!!

Good Shock, no issues
Been using for over a year, works well. I use the recommended amount normally but after a load of grandkids I'd recommend a bit extra.

Good shock for our hot tub
Good shock and doesn’t smell like traditional chlorine! My skin is better and not as drying as some shock. I would recommend for the size you receive and affordability!

Yup, finally got a bad lid too, but I solved it without destroying the container!
TL;Dr for lid problems: Smash the side of the lid with a hammer all the way around to loosen it. The product is a good value, the first one I bought I definitely struggled with the lid but mainly because I couldn't reasonably get the red tab high enough. The second one I was more prepared but despite knowing exactly what to do the lid wouldn't budge. For anyone who says they never had a problem with the lid: you got lucky however many times in a row. The red tab was out of the way but the lid does not budge whatsoever. And I'm the person my partner goes to for opening difficult things. I tried a bunch of stuff without outright destroying the container but what eventually worked was blunt force trauma all the way around the lid. I originally had a wrench to clamp open the red tab, so I took it and smacked the side of the lid all the way around in frustration. After one more good tug, it finally gave. Just in time to do my weekly chemicals tomorrow!

excellent
I've previously given high marks for your product but either by coincidence or side benefit, my hot tub had a small leak for at least 10 months. After using the cleaner one time the leak had stopped.... super product!!!

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. 2024 Will 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!

A little does a lot
I got this to use for my Coleman SaluSpa hot tub. I don’t have to use a lot to keep my hot tub balanced. I’m a new hot tub owner so I had to do research to figure out what was needed. I add some into my hot tub after using it and have noticed how much easier it’s been to keep my hot tub clean.

Despite using less than recommended, this stuff smells so strong! Wouldn’t buy again. The smell lingers for days. Concerning.
