shock question

[Elle]

We are down to using our tub about 3 times a week (from the beginning stages of daily use).  My water is crystal clear and balanced nicely.  Do I need to shock once a week if everything is reading correctly?  My dealer says to shock only when the bromine levels drop below .5ppm.  What do you experts think?  I'm shocking with dichlor and it tends to elevate my bromine to 10ppm for days after a shock.  I use just under an ounce to shock for my 400 gallon tub.  Too much?

I have gotten into the habit of shocking just a bit each time I get out.

I recommend shocking if you use your spa 3 or more times a week.

An ounce sounds like a lot. To shock 400 gallons, 3-4 TEASP00Ns should be adequate, not sure if that measures one ounce or not. It is important when you shock to leave the cover off for an hour to allow off-gasing to occur.

Stuart, are you saying that you add MPS each time you use the spa or are you adding a small amount of dichlor? Adding a small amount of dichlor after using is not by definition shocking but sanitizing.

3 to 4 teaspoons is about an ounce! I use Enhanced shock so it is adding Chlorine at the same time.

I'm no up with your wacky imperial measuring. Metric is so much more logical......

You should shock weekly IMO. Run for 15 minutes with the cover off and jets on high speed.

Look at it as more proactive than reactive. We don't check our oil in our cars once the oil light comes on hopefully...
