  • Amazing!
Size: 8-Weeks (16oz)
Stuff works amazing! At first I had clumps of orange but later found out it was the rust from the well water. The next day my hot tub was so clean and the side walls were silky smooth!

  • Empty pack.
Size: 4-Week Kit (8oz)
I ordered the 4 pack. However one of the packs came empty. It wasn't cut open, it looks like it just leaked out but there was no water dmaage to the box. Disappointed that I paid for 4 but can only use 3.
