I’m wondering if it’s normal to have a lot of air bubbles when you increase the pump speed. A little while after increasing the speed there’s no bubbles from the return jets and before I increase the speed there’s no air bubbles in the return jets. But once I turn the pump up I get a lot of bubbles and then it settles down and there’s no bubbles.

It is hydrogen gas from your SWG.

It's normal then? Even though the pump was running for several hours before I increased the speed?

Yes mine does it too. If I run it on low speed, some bubbles might come out, but as soon as I turn it up, a big burst comes out. Bubbles get stuck in your plumbing and a stronger flow pushes them through. To test this, try lighting the bubbles as they break the surface. If they "pop", they are hydrogen and come from the SWG.

You can see them flash at night, during the day you'll just get the pop.
