What if this doesn't remove my stain?
We have many happy customers who are able to fix the cloudy water issues with their hot tub. That said, if this product wasn't the solve to your problem, we provide a full refund or provide you with the right chemical for the job.
Can this help defoam my hot tub?
Yes! While we do recommend having a spa defoamer on hand for spot treatment of heavy spa foam, we recommend a clarifier to help remove the cause of the excessive foam. Many aren't aware that foam buildup in hot tubs is caused from dirt & contaminants in the water. Our spa clarifier attracts the micro contaminants together so that they're large enough to get snagged by the filter.
How often should I use my spa water clarifier to prevent cloudy water?
If you initially have a cloudy water issue, we recommend using daily until the water is clear. Once you've resolved the cloudy spa water issue, we recommend using 2x a week to avoid future cloudiness & foam buildup. If you use the hot tub often, you may want to consider using our clarifier 3x a week.

Better than I expected!
I am a beginner to all things hot tubs and chemicals. To be honest, I feel pretty fancy dipping a test strip in the water – like a bonafide scientist, haha! There are chemicals to add like chlorine or bromine (which appear to be practically the same), ph increaser or decreaser, alkaline increaser or decreaser, foam decreaser, shock, and clarifier. For the purposes of this post, I gained some experience with the other chemicals, and then it was time to try the water clarifier from Mav Aquadoc. If you have a hot tub or swimming pool, you should give the Mav Aquadoc Spa and Hot Tub Water Clarifier a try. Again, this was my first time using a clarifier and I quite liked it. The other chemicals I’ve used came in a granulated form, so I was surprised to see this arrive as a thick dark blue liquid that seems to not have any smell. I used a small glass mason jar with the ounces marked on it to measure out 2 ounces. I have a 500 gallon hot tub and the directions were for a larger 800 gallon tub so I had to adjust. In it went and I was a little surprised to see so much of the blue residue staying back in the glass. I rinsed the glass a few times in the water to get the rest out. It seems to me I would have wasted some of the product had I not done that. I checked the water later that night and also the next day with the sun shining through to see if I could tell a difference. My water has not been very cloudy and was not at the time I used the clarifier, so one might think there wouldn’t be much of a difference. It turns out, there was a huge difference! This water clarifier worked great! When the jets aren’t going, I can see every spec of sand that magically found its way into the hot tub. The Spa and Hot Tub Water Clarifier bottle I received is about the same size as the bottles I use for other purposes in the tub. Because the bottles are about the same size, but I need to use more of the product than the granules of the others, I think I will go through it quickly. Given the price of the others, at least I know they will last some time. I’m not so sure how long this will. I plan to continue using it, although I will wait until my water is cloudier to help it last longer. I am only giving it 4 stars because I'd like the product to last longer.

Great for cloudy water

Combined with the defoamer, this stuff is great for turning the water in our hot tub clear, clean, and beautiful!

Works as expected
I never used a water clarifier in my spa before so I thought I would give this a shot. I don't use it to replace balancing chemicals but just in addition sometimes. My spa was balanced but still has a little cloudiness. I used this and it took about a day, but the water was clear again. I was happy with the product and how it works. The cost was reasonable.
