Welcome to our forum.
Are you sure its chlorine and not bromine? Â What about Alkalinity?
Are you using Tri-Chlor pucks in the feeder? Â Usually chlorine in hot tubs is in the form of granules with the name Di-Chlor. Â If people use a feeder it is usually with bromine. Â It is my understanding trichlor is for pools and voids most tub warranties.
Yup. Get off the Trichlor. Â You can use Bromine or Dichlor to sanitize your tub. (I prefer Dichlor and suggest you use a post soak Dichlor dose with a weekly MPS shock). I'd dump the water. clean the filters, (or perhaps even pick up a new one or two) and start fresh with the dichlor routine. What brand of tub is it? Â
