I fired up my SWG (Pentair Intellichlor IC-20) for the first time yesterday and noticed that while it was running, bubbles were effervescing out of all the returns. I know this has been discussed here in the past, but I was under the impression that these bubbles were supposedly so small that they were hardly noticeable. These bubbles are quite evident, much like you would see in a clear glass when pouring a can of sprite into it. I just wanted to refresh the discussion with my observations.
Not that I'm worried that anything is wrong, just would like to hear other's experience.
