What kind of shock treatment

[realjet]

I am new to spas and wanted to know the difference between non-clorine shock and clorine chock. I use granulated chlorine. What shock should I use? I have a Nordic Crown.
Thanks

use your chlorine to create the SHOCK, at a minimum rate of 1 teaspoon per 100gals.(that's for clear water, hazy/ cloudy water may need more)

Once adding, run pump for 10-20mins with cover open. then close.

Do once a week if using spa 3-4 times per week. Once every 2 weeks if using spa less than 2 times per week.

I have used both methods extensively.  I prefer non chlorine shock, but I like to get my chlorine level up to between 3 and 5 ppm once per week just to get that extra sanitation.  I found using chlorine to shock would keep me from being able to use the spa for at least a day after.  It also sends CYA levels through the roof.  I also believe that MPS does a more complete job of oxidizing.  Non chlorine shock adds a little to TDS, but my water stays in good shape unitl I change it every four months.  I now use one tablespoon of dichlor and two tablespoons of non buffered MPS for my 485 gallon spa.

There is also a product called Enhanced Shock by SpaGuard, I believe, that is a mixture of dichlor and MPS.

RE: What Kind of Shock Treatment?

Well, electric worked for me.  Although when I close my eyes,  everyhting is  kinda squiggly (but on the plus side, the voices have quieted down quite a bit).

YMMV.

I know this one, I lnow this one. Pick me Pick me.

One has Chlorine in it and the other one doesn't  

And isnt "chock" what the teacher uses to write on the chockboard?

Sorry, couldnt resist it

Seems to me that a non chlorine shock makes a lot more sense in the winter/colder climates.

With a dichlor chock (20 grams / 1000 litres) you really should leave the cover off for an hour to allow proper oxidizing and prevent the chlorine vapors from seaping into your cover.

MPS effectively oxidizes in 15 minutes with no residual.

Less time with the cover off = less time with the heater on.
