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!!

Hard to open, but nice not to have to order a bunch of small bottles

Good product worked well

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!

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)

Yes, the lid is a little tricky. Not as bad as some make it seem, but not something I want to open every time I use it. Here's a tip. Take an empty container, wash and dry it well, and transfer the contents. Here's the real trick. The labels from the original container EASILY transfer to the new one.

We purchased this 5lb container and, like many others, found the lid extremely difficult to open without damaging it. Once opened, it never sealed properly again, which made safe storage a concern.We stored the container in a metal outdoor cabinet we’ve used safely for years. Unfortunately, we later experienced a serious incident related to chemical reactivity that caused property damage. A safety inspector explained that some pool chemicals, when spilled or exposed to common materials like cardboard, can become unstable.This experience highlighted risks we hadn’t considered — especially how important it is for the lid to seal securely and for consumers to be aware of potential reactivity.We hope the packaging design has been updated since to allow for safe opening without compromising the seal. Regardless, store with caution and away from anything that could react with the contents.
