Red Sea Reefer XXL Ultimate blowing bubbles into the tank?

[danreef55]

I installed these on my system and fired up the pump. It is discharging a huge quantity of bubbles. Does anyone know a solution to this issue? Any assistance would be greatly appreciated.

Is it an eductor? If so, ensure that the tips is low enough in the water that it is not pulling air via venturi.

thanks I will double check

Either the eductor is sucking air, or air is being sucked by the return pump if it doesn't stop on its own after ~2 mins (leftover air being purged in the plumbing)
If it's the eductor then you will need to lower it, if it's the return pump then you need to increase the water height in the sump or move the intake away from a wall/baffle if possible.

Thanks c_awol
I can rule out the return pumps. Will check the venturi

Mine was very finicky and hard to get below the water line.

 

[danreef55]

I cannot find a venturi hole on the line. Also it is impossible for me to bury it deep enough. Is it possible that I am pushing too much flow through them? I think I am going to scrap this idea and just build them myself.

The backside of the eductor, the discharge nozzle, should have an annular opening that is meant to pull extra water through the nozzle via venturi effect. If the nozzle is too close to the surface it will also pull air. See if you can see an area on the backside of the nozzle, not the loc-line, that is sucking air.

You can also slow down the flow from the return pump, though this kinda defeats the purpose of having an eductor.

If you can't get it lower in the water, you may be able to either block the topside of the annular ring, or add more.loc-line sections.

I doubt it is too much flow, maybe your display tank fill level is slightly low?

I barely got those nozzles below the waterline in my tank.

I have two Red Dragon ECO 5 130w return pumps and two Maxspect gyres so I am going to build my own return exhausts. I will hold onto the Red Sea's in case I need them later. Thanks for all your input it is greatly appreciated.

I would need more loc line, so I am going to build my own for now. Thanks
