What quantity to use for the small hot tub?

I have a 500 gallon hot tub and I use 2 oz a week

Can you use this in a Inflatable hot tub?

Yes, you can use it in an inflatable hot tub, just be sure to use the correct dosage according to your volume of water. A clarifier basically chelates particles in your water so they can be filtered out through your pump. As long as your system is working properly, there should be not problem.

This work good on inflatable hot tubs?

Yes. I use it in my inflatable and have for about 2 years. Works great.

Great Product

Wow works great and cheap. It made the water cloudier the day I put it in, but then next day its crystal clear. Looks even better than a fresh fill somehow.

Clear water

Used another product originally and did not clear up water at all. Purchased and tried HTH Spa Clarifier. This product worked great. After first filtration cycle, there was a ring around the tub with much scum, assuming soaps and lotion in the water from suits and bodies. Wiped clean, changed filter and ran again. Same thing with ring around tub but water was very clear. Rinsed filter and ran one more time. Excellent results. Would recommend this product to make water crystal clear. Make sure to rinse filter or change out as noted above.
