My waterfall feeds into a 90 gal. tank/pond. So far I have it going
off at 12am and on a 7am. Am I prolonging the life of the pump(I'm
sure it's a small one and not overly expensive) or is this just a myth
and should I just let it rip 24/7?

Any thoughts?

All the best,

Your fish need to breathe 24/7. So leave it on, assuming you don't have any
other aeration.

Although I find mine kind of annoying at night with the windows open. It
gets really bad if I let the pond level drop an inch or two. I'm surprised
one of the neighbours hasn't shot me yet.
