Hot Tub Fiasco

For several weeks I was unable to use my hot tub because of a heart monitor I was wearing as it was water resistant but not water proof...  Now that the 30 days are over, I am once again able to use the hot tub.  Typically, after a long day whether tired from working or not, I like to relax my body is the hot water of about 103/104 degrees...  and, getting into that hotness has to be done slowly and carefully but once in, I am usually in the water for about 30-45 minutes and run the jets about12-15 minutes as it makes one's body super hot.

Every other week or so, I pour into the hot tub about 1-2 cups of non concentrated bleach to purify the water as best as I can...  knowing that I am going to replace the water about every 3-4 months.  This last time of pouring in the bleach and setting the jets to CLEAN, I noticed that foam was being created and since there was nothing I could do about it at the time, I just went back upstairs.

The next day, I wanted to get into the hot tub and once I lifted up the cover, noticed that there was still some remaining foam but lowered my body into the hot water anyway.  And, once I turned on the jets, foam was created quite easily.  After a few minutes with the jets on and pushing away the foam, I decided to turn off the jets...  the foam gradually dissipated 

Tonight, I will get into the hot tub again and I wonder what will happen and how long this foaming condition will last...  I also wonder why the bleach I poured in caused this to happen...  but, since I am going to drain the water and refill the tub in a couple of weeks, I am not that concerned...  it is just a minor aggravation and/or annoyance with which I can easily deal.
