Hey Sajjad

How've you been?

It's important to note that 38 GPM is the peak flow. Once you put other
things on there, including tubing, you're going to start losing flow to
pressure. You'll probably, at maxmum, get about 75%% out of that.

That said, 38 GPM = 2280 GPH. That means it'll (again, this is at peak)
turn over the pond seven times in an hour. Five times in an hour is what
you have in an average aquarium. For a 300 G pond, though, I'd have rated
you with a 750-1000 GPH pump, depending on what you want to do with it.
(I.e., if you're going to power a filter, you could use a 500. If you're
going to power a waterfall, a 1200 or higher may not be a bad idea.)
So... is this a little big? Yes. Are you talking Niagra? No. Should be
just fine.
