We carry hot tub chemicals that you can use in most brands of hot tubs.  Bromine or Clorine.  We just added a new natural sanitizer if the others bother your skin or you just want to use less chemical.  We also carry start up kits with the chemicals we sell.  Right now we just carry filters for our Softubs.   Our Chemicals are kept at the front of our Mens Department right by our Softubs.
