Hi, I have been lurking here for quite some time before joining up. Amazing info.

My spa was cleaned last week by our pool company and its foaming like my husband after a Canes loss

Pool store results are

br 4.0
ph 7.5
alk 70
ch 130

any ideas what could be causing this....possible they did not rinse out all of the purge goop?

Yes, if they cleaned the spa with a spa purge product, it is very possible they didn't completely rinse it out. Such products have powerful surfactants and they can suds like soap. You should be able to scoop out the foam/bubbles and that should reduce the foaming.
