Welcome to our forum.
Nope, that is what the HS manual says... mine says it too. Â I chose to use the dichlor after use and MPS weekly program instead. Â Works great for me. Â Never tried it the other way.
What then, I wonder, is the idea behind the MPS daily/dichlor weekly routine? Â
So how much dichlor should I use after each use?  The Jetsetter is only around 225 gallons and for weekly shocking it says to use only 1 1/2 teaspoons.  And if I use dichlor for daily use, should I use MPS for weekly shocking or stick with the  1 1/2 teaspoons of Dichlor?  I didn't know owning a hot tub was going to bring back bad memories of chemistry class!!
