Getting bubbles out of returns only when SWG is generating?

[ForceEdge]

Not sure if this is a silly question, but I just had my setup reconfigured and I don’t think I’ve ever noticed this before the reconfig, but now I see whenever the salt water generater is generating chlorine, I’m seeing bubbles come out of the returns.

When I turn off SWG, no bubbles.

Not sure if you can see in the close ups but first SWG picture shows waters clear no bubbles, once it starts generating water looks cloudy/bubbly.

Third pictures of salt water generating has those two air pockets up top but they just stay there and don’t move or get bigger

I also noticed once pool heater goes on, I think I get even MORE bubbles. And you can see like clouded water coming out of returns in picture of returns if you look close

Is this all normal?

Is there a way to fix that?

FE,

Perfectly normal... There is nothing to fix.

You can turn the cell with the plates down and see if that helps..

Thanks,

Thank you! So the heater by itself can create bubbles?

And the SWG can also create bubbles when on?

Why is that exactly for both?

SWG creates chlorine gas and hydrogen gas. The chlorine dissolves into the pool water quickly. The hydrogen gas is the bubbles you are seeing.

What about the heater creating bubble?

I don't think the heater is creating bubbles. What may be happening is that the water is just warm enough for the SWG to produce chlorine, and with the heater on (and the water then being warmer) the SWG gets a bit more efficient.
