Tiny bubbles

[jkayca]

Hi folks,

So opened my pool this week. A complete mess with algae but it's slowly coming together. It's nothing I haven't had to tackle before. Some chlorine and a good hard scrubbing has taken care of most of it. One problem I'm seeing this year is from my SWG. A Hayward T15. I'm getting lots of tiny bubbles coming from the returns when it's active. I cleaned the cell out before using it so I'm at a loss as to what's going on. My salt levels look good. Any advice?

Thanks,

FYI - back washing the sand filter every day.

Those bubbles are normal, you see those when the cell is generating chlorine.

It seemed to be quite a lot though. The pool turned very cloudy. It has subsided though so I'm not so worried any more.

It's hydrogen gas. Hydrogen is a byproduct of the chlorine generation process.

The bubbles are comforting to me. Means a working cell at a glance. Though an absence of bubbles doesn’t necessarily mean it’s not working.
