Chlorine is like coffee at a restraunt - I sell 2# for $12.50
Is it the HS version for $12.50? Who makes the chemicals for Hotspring by the way? Just curious.
Here in dayton, I just bought 70# of Di-Chlor at sam's club for $100.00. I just keep refilling my old bottle when needed.
Be careful when buying your chems at big box stores. Sometimes you're ok, but they are not always the same, so what may seem like a good deal may not be. The other concern when buying dichlor in large buckets like that is that they are mostly made for pools, and very likely contain other chemicals like stabilizers (and in some cases fillers). Make sure you read the label and know what you're looking for.One last note, and I'm a dealer so I'm a bit biased, but buy from your local spa dealers. You may spend a bit more here and there, but in the end, they are the ones you are going to go to if you've got problems.
