Are these what the Hydrogen bubbles look like from a SWG? Zoom in on pic to see then.

I’ve noticed that when rpms are at 1000ish and I bump it up to 2400-3450 my first return closest to pool spits out these bubbles for about 10 seconds or so. When I go from a high rpm to a low rpm, the bubbles appear again.

That is what mine look like. Likely the hydrogen bubbles. Apparently you can put a lighter above them and they will pop to confirm.

My swg controller just went belly up in the on configuration when with pump off. Noticed huge bubbles glugging out of the returns, later thought that could have an interesting "pop" :shock:

I don't know what the cycle time is for the Trueclear. If you watch the bubbles you should see them disappear 30% of the time if they are coming from the SWG.
