OK Dealers and service techs....Need some opinions please. I have a hot tub that when in use has excessive aeration and is solid micro bubbles when in use...The tub supposedly has been this way since new (6 mos) and the water has been drained 4 times already trying different things such as filling with a pre filter and using the vanishing act pillow...de foamer, etc...
The tub is not a salt system and when the water is tested it is in check with TBR,FCI,Alk,pH,Hard. We tested the tap water which is city water and not on a water softener and has no Sodium on the readings.
When the pumps are shut down and the tub sits for a min or two it is crystal clear. There is no physical buildup on shell surface and the filters have also been changed just to eliminate the possibility. We are talking about aeration bubbles and nothing more...No foam what so ever. Kinda puzzled... Thanks for any advice
