The term "flow accelerator" is kinda tricky. People think your actually getting a higher flow rate but you aren't. Flow rate = Velocity*area. So by changing the nozzle area, you can change the velocity of the water coming out the nozzle, but the flow rate is still the same.

Will an eductor not pull more water from a venturi effect. That is what j was talking about. Some of the inline vendors have them listed as accelerators, but they are really penductors/eductors

Yes eductors work.

Also called flow amplifiers.

Thanks to Henri Coanda
(brilliant man

yes they work. Flow accelerators are just different versions of eductors that are on locline.

Eductors usually have more linear flow patterns, Flow accelerators have more diffuse wide flow patterns but dont move quiet as much water as eductors.

I use flow accelerators for really long straight runs and flow accelerators for flow thats going to hit coral within a foot or so.

I have 8 flow accelerators and 2 eductors in my tank now and I love the flow.

Do you have any on the bottom facing up. Just wondering if they will suck sand through them if they are to close

I have them higher up so sucking sand isnt an issue but I do have them within 4" of the surface and pushing 1000gph though them they dont suck air off the top

It depends how much flow youre pushing through them and how close they are to things.

We use them here at SEA Atlanta. Come and see.
