It does sound like what we call white water mold. If that is what it is, you will need a lot of chlorine (more than superchlorination) and some kind of spa purge. Drain and refill. clean filter.
It almost sounds like biofilm. This is a new spa?
Definitely sounds like white mold. Notoriously bad stuff. You probably should perform a decontamination procedure. There is one posted on here somewhere.

I do have a foam issue, but I believe it's because of friends getting in the tub with detergent residue on their suits. I use defoamer and that solved the issue, but only temporarily.
