Great scale prevention
This not the first time I have purchased this product. It is essential for the type of high calcium water in central MO.
I add it 1 time per month to decrease scale deposits on the spa walls. I haven’t developed any issues with pump or jet blockages.

Good Prices
I got everything that I ordered in a timely manner. I feel that the spa filter prices are the best anywhere, including Temu.
I'll be ordering my chems and filters from you guys from now on..Cheers!
