This is the strongest pump they have at htg supply it's 60$ and it's 12 watt has 8 outlets and does 25 liters per min...I have a 45 gal res and I know it's supposed o be 1 watt per gallon ...it's only 12 tho but it says its a new pump with more power and it's goig in my room so it can't b too loud. Anyone have this pump it's not the commercial ones but it's active aqua let me know if u think it'll work
