Well depends on the tank size. 200 to 450 Id say reeflo super dart/snapper hybrid gold. $300 to $400 depending on who you buy it from.
I use the 4300GPH impeller. little Most DC pumps don't have this.
Mine is quitter than my skimmer pump which is a DCT 15,000 jacod/jebao
Next choice if money wasn't much of a factor over $1K would be a Royal exclusive Red Dragon 3 Speedy $$$ in 4500, 500 gallon 5000, or 600 gallon tank 6340 GPH
dead silent you turn them on and wonder if they are working until you hear water moving in tank. NICE!
