I have been using this product for about 6 or 7 years in my 250 gal. hot tub. All I can say is it works as it should. Even on water changes when the crud builds up on the water line---this stuff simply removes it. I maintain my tub with it and scum lines never occur.

Your product seems to be good, but I have nothing to compare with except rinsing with water 👍

I absolutely love this product! The smell is great, coconut scent that reminds me of Hawaii! It cleans the water scum line and clarifies the water. I use this to get rid of foam now too, it works way better than regular antifoam.

Very happy with this product.

SpaDepot is the best. I always utilize them for all my spa needs. I recently had an order that arrived with some damaged product and they sent out replacement product that same day, no questions asked.

I wouldn’t go anywhere else.
