Added Salt to get pool running for season and now the tub foams

[Silver_2000]

HI

Its warming here so I added salt to get back to 3000 ppm
the water was clear before and is pretty clear now except for the pollen and spring debris.

When we run the hot tub the water seems to foam. Ive not seen that before.

The chemistry is pretty stable. PH hasn't changed in months. Ill run the rest of the tests today but Im curious what could cause the water to foam when we turn on spa boost ...

Well even though I didnt believe it fixing the CH fixed the foaming ...
