The sequence series of pumps will more than pay for themselves because of their low wattage draw per GPH.
I just ordered the Reeflo DART.
I got it for 200usd and it's 3600gph
I would try to turn over the pond more than one time per hour, because when the Bio-load increases just by the fish growing you'll wish you had.
I will say with your vorti you could go for a smaller one now, but you'll be buying more GPH later.
They are totally re-buildable...so you might consider a used one...
