Hmm interesting idea. Do you think the copper would damage the fiberglass? Maybe I could line the bottom of the copper tube with something like high heat silicone to protect it?

Funnily enough I did check out aquarium supplies too, but I don’t think I went to hyper specialized stores yet that are for super large aquariums. Those might be too fine of bubble though, turning us into a seltzer.

Thanks for the suggestion! I’m going to explore it more.
