Aquadoc Non-Chlorine Spa Shock for Hot Tub - Chlorine Free Treatment & Enhanced Shock to Assist Bromine - Suitable Oxidizer - 5lbs

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!!

Tore out the red tab and it still won't open. The lid doesn't rotate at all. Even with the red tab gone, it's completely fixed into place.Edit: they've reached out and offered a full refund, so I'm switching from one star to five since they've at least got excellent customer service.

The media could not be loaded. So I love how this product is fast acting and extremely effective at keeping our spas water clean and clear.The Water clarity is awesome! It comes in a great size that last you a while.I find it super easy to use once you get the lid off which is probably the biggest hassle....The product itself once you get past that difficult lid is worth every penny!My spa is cleaner than before and I will continue to use this since it works great!! (At least once you get past that pesky Lid)

Addendum: I wrote a review months after purchasing this product about my frustrations with the inability to open the container. The company reached out to me immediately and issued a refund for my troubles. Excellent customer service! The product worked great, so I’d say it’s worth buying and shooting your shot at getting the lid off. If you struggle with this, reach out to the company and they will make things right.Initial review:I saw the reviews of others saying that the lid does not come off. I figured that had to be a user error and there had to be a way to get it off. Bought the product anyway. Discovered that the reviews are true: there truly is no way to remove the lid. I ended up having to drill a hole in the lid, therefore the next time I went to use it, the product was a solid block that was not usable anymore. The product itself worked well, but terribly designed packaging. Would not recommend it for that reason.

The media could not be loaded. 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!

I use this for my 4k gallon swim spa and it works great. Keeps it clean and clear. Doesn't affect any of the chem levels. We dose once per week and go through one tub per month. Totally worth it.

No one, but no one, should buy this product in this packaging. In theory, you use some sort of tool to lift the "catch" out of bucket top from the lid and then unscrew the top. In reality, the top is screwed on so tight, there is no way to make this a one-person job. You need one hand to hold the bottom, another to torque the top, and then a third to hold the "catch" up, and that's if you have enough strength to actually loosen the top when the "catch" is in release position. No one I know has three hands, so it turns into a two person job, IF you have a second person. As anyone who has ever tried a two-person job that involves any amount of force/torque, you don't want either person holding a tool like a screwdriver. Just a bad, bad design that just doesn't work and is bound to draw blood, if not poke an eye out. I ended up using a utility knife to cut a big hole in the top close to the edge, then cut the top edge through the lip of the bucket and poured the contents into my old 6 lb container that opens and closes with a simple twist.

The product works great, we are on our 4th tub.To the people who say they can’t get the lid off…you must be special. I have NEVER had an issue getting the lid off, and I’ve never had to use a tool. You break the seal on the red lock first by squeezing very firmly up and simultaneously start twisting it open back and forth (it does not lift off.) It’s not hard.We keep a measuring cup in our locked deck box with the other chemicals, and shock when needed, usually 1/4 cup for our size tub. Run jets with top open for 30 mins and voilà. Bromine levels stay steady.
