Some of you may have seen in my build that I was using a new type of loc-line nozzle which ultimately has significantly increased the flow created by my existing return pump. Originally I planned to make them my own and opted for the clean look of a fabricated one for ~$20 with some extra features. The fabricated ones does have distinct drawbacks I suspect that I can go over later. However, for my QT I figured I'd try it out DIY style. The concept is... high pressure/flow exiting the nozzles into the display naturally draw in low pressure/flow from around. This design harnesses that slow ambient water and channels it in your direction. The net result is a noticeable increase in flow without adding bulky powerheads. Originally I saw an air based concept on shark tank that gave me the idea, Dyson fans already use it, and naturally someone smarter is already making them for water.
