Best filter and pump for 125 gallon preformed pond

[Alittleamused]

total newbie here with a 125 gallon preformed pond from one of the big box stores. The filters they try to sell for these ponds (submersible) appear flimsy and not efficient. I plan to keep two comet goldfish and filtration I know is important. Can someone please point me in the right direction. Oh by the way wish I would have went bigger already say 1000 gallons

I just use pressure filter in my stock tanks .The one is 300 gallons and it works great on it .

When I put my first preform pond in (approx 165 gallons) I used a Pondmaster filter. They come in several different sizes and are submersible so you dont have anthing right outside of the pond.
