Spa Hot Tub Chemicals

What we have are several bottles of treatment by Baqua Spa. Some bottles are new, and some have been used where there is a third of the chemical left in the bottle. We once used Baqua and they have a very good product. I could not see just throwing these out and thought maybe someone out there could use these for their system. Included is the Calcium Hardness Increaser, Total Alkalinity Increaser, Foam Disperser with Vitamin E, Sanitizer with Stain and Scale Control, pH Decreaser, Metal control, Oxidizer, and Waterline Control Some of these bottles were $25 each, others $15 and the larger two were $40 each. Hope someone can use these. Listing will be removed once it sells. Thank for looking!
