SLAMming my Spa - still getting bubbles

[Skurzban]

I have been slamming my spa with calcium hypochlorite. Took a day and a half but water is consistently clear now and holding 24 ppm chlorine. However, I noticed when jets run I still get some foaming and the bubbles carry grime. Do I need to keep SLAMming until they go away too?

I am not a spa person but lets ask @RDspaguy

I would use Ahhsome. Sounds like biofilm to me.

Thanks. I have used Ahhsome previously and other "purge" items regularly but the spa has become increasingly tough to balance, so I figured I would SLAM it. Draining now and will flush the lines and hopefully that works.
