Bubbles in the water
My kids got in the hot tub with my husband briefly the other night and the water is foamy and has a lot of bubbles. I realized I had recently washed their swimsuit in the washing machine and assume the bubbles are a result of that. How do I get rid of it? And also I'm wondering if you're just not supposed to ever wash swimsuits or this will happen? Sounds like a stupid question but I have no idea.

Nature2 stick and Bromine
I just fill a new hot tub 5 days ago and let the Nature2 mineral stick in it while I used bromine sanitizer. I realized u shouldn’t have done that and took the stick out. Do I need to drain and refill since it was only 5 days? My hot tub also has an ozone system. Is ok to use bromine sanitizer with this?
