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.

Exactly as described
Worked like a dream for our 6 person hot tub. Need to buy again!

Great product
Had a film on the top. 2 hours later totally gone!!

When others failed this worked.
If you are tired of buying products that's don't work then this is the one for you. I have been fighting green cloudy water since I bought my hot tub months ago. I tried different filters and shocked and spent way to much money on chemicals. This clarifier fixed it. A little chlorine and the occasional ph adjustment and this clarifier and my water stays clear all the time. I have two filters and switch them every few weeks. When I pull them I just wash them with my electric pressure washer and they are ready to be used again. Water problem solved.

cleaned my swamp in 12 hours.
So my kids are home from college, and for the last week they, along with their grimy filthy drunken friends, have been soaking their nasty carcasses in my pristine hot tub every night. It didn't take long for me to notice that the tub looked like it was filled with an RV's wastewater tank. It smelled like rotten turtle soup, and I thought for sure I was going to have to drain it, and pay a hazmat fine to the city. But lo and behold, 2 ounces of this magic miracle elixir, and running the ( cleaned ) filter for 8 hours, and the pool was good as new. I mean, I won't be baptizing any babies in it or anything, but it's clear, and smells like a normal hot tub again.

Great product
Doesn't seem to disrupt the PH/alkalinity of the spa. Water is much clearer, less foaming, and water smells good.Made sure that PH, alkalinity, and bromine levels were good before adding the Clarifier.Used hot tub about an hour after adding it and allowing it to circulate.Water feels softer, looks clearer, and no itchy skin after getting out.
