Call me paranoid: do I have to worry about hydrogen build up under the solar cover?

I noticed a number of bubbles under the cover above the return after the SWG ran for a few hours today. Should I be concerned?

I wouldn’t think so but might a good experiment

My SWG has been running under my cover for the last month and the past 5 years during spring and fall.. Nothing to worry about

The bubble, more specifically the bubble dancing around under the cover, was how I knew my pump was running for 5 years while looking from the patio doors.

Hydrogen gas cannot detonate without a source of energy and the presence of an oxidizer like oxygen. Heat is insufficient. What cause SWG explosions to happen is that hydrogen gas AND chlorine gas build up together in the same volume. H2/Cl2 mixtures are self-detonating and don’t require much more than a little warmth to explode.
