It's for pushing water not sucking tho? Unless ur return pump turned off and it siphoned. But I am going to put a check valve on my return line to prevent this

I have them on my tank.Haven't used that brand but if it is the same principle they do work to increase flow.

water gets sucked in from the back side, hence how these work, if a fish is swimming near your loc line return in the display tank, there is a chance he will get sucked in - just like mine did.

but sometimes this aquarium is all about taking chances. it seemed to have worked for me though!

Ahh kk. I guess I'll just stick with the typical flared nozzle then.

if it gives you re assurance to try it... it was a tiny little fish - if you have it - give it a try. I know I wasn't exactly blown away by it
