Our new hot tub was originally filled on 2/8, so the water isn't that old yet. I've kept the water balanced and properly sanitized from the beginning, and my wife and I use it every day, without suits. We've been very careful not to introduce soaps and other things. Last Friday, 3/17, we had two guests use the spa for about 20 minutes wearing their bathing suits. Since then, when we run the bubbles (this type of spa does not have jets but puts a lot of air through hundreds of holes around the circumference of the base to thoroughly stir the water) the surface of the water foams up fairly significantly, and the foam will stay around for a bit, although it will eventually dissipate after about 10 to 15 minutes. I'm not ready to change the water for a while yet, so I'm wondering if taking the bromine up to shock level, say around 25 ppm would do anything to clear the soap out, or if not that, if I can use a flocculent without messing up the water chemistry. By the way, based on reading here, I thought that a Calcium Hardness of 150 is enough to prevent foaming.
