Thanks HHT. I really don't think I have a problem but I was more curious if this seemed normal with both pumps on high all jets open (90 of 'em) and air injection running. Also nobody in the tub to slow anything down. I doubt that it is a soap problem, as I am the only one using the tub and I am always in commando. It has been about 2 1/2 months since water change, ph=7.6, ch=180, ta=90 salt level=3300 (this is a little high), usage is about every other night for about 30- 45 mins. The foam starts to dissipates almost immediately as you turn off pumps and/or blower, leaving no residue on top of the water but cloudiness in the water which clear as it settles.
