Welcome to our forum.
... it is hard for me to still understand why many spa and pool owners buy chemicals from an on line source or a big box store. ... Just something to ponder...
...that is more economical than the spa shop down the street? I pay $27.95 for 5# shock. Is that really high or is it in the ball park?
the same place wants $20 MORE a bottle for the same stuff I buy at Home Depot for $7.95?
