I have a brand new Cal Spa hot tub. THe water chemistry is within range. When the pump is running and bubbles are generated, I get cream to light brown colored bubbles forming in certain areas around the tub (when the pump shuts off all bubbles including colored ones dissappear). 90% of bubbles are bright white but the other 10% are colored. I use the tub on average twice a week with 5-6 people per time and for periods of 2-6 hours at a time. No-one really "rinses" off before getting in or takes off makeup.
Should I assume these colored bubbles are just oils? When I circulate each day to add chemicals, I continuously scoop the colored bubbles out but they just keep coming back in the same areas. How do I get rid of theM?
Also, any hints as what to do right before or right after a long period of use to keep it from clouding up?
