Whenever I turn on my jets my hot tub ends up looking like a bubble bath full of fizzy foam. Not just a little bit either, I'd probably be ok with that, but it ends up getting like 4 to 5 inches thick across the entire surface. If I turn off the jets, the foam starts to go away and after about 5 to 10 minutes the water is back to being crystal clear with no foam at all. I've done some reading and have tried a few things, but all to no avail. The only thing I haven't done is a drain and refill only because I just did it about a month ago and don't want to have to do it again so soon. I don't think my well pump can handle draining and refilling this thing every month. We use it about 2 times a week, or less, and its usually just 2 people.
My water test results are below. All the levels seem ok to me, but there's gotta be something I'm missing. I'll also use Leisure Time 'Enzyme' and 'Bright & Clear' sometimes, as needed. Please take a look and let me know if you have any ideas...thanks!
