Welcome to our forum.
I will neeed to do the same thing to a used spa I bought. Can liquid bleach be used in place of dichlor.
PotomacG: I have a few Q,4. Add at least 100 ppm chlorine to the spa being sure not to allow the Dichlor to come into direct contact with spa surface before is dissolves. How would one do this???10. Drain and flush the spa.What about those places that are near impossible like the air blower lines?AND11. Clean the spa surface with a surface cleaner approved for you type of spa shell surface. Rinse the spa thoroughly! I have no idea what kind of surface cleaner, any sugestions? Brookenstein, where you responding to me or jfish63?
