Little air bubbles

[pkaufman]

Coming from the pump back into the tank, I have many tiny airbubbles comming in. They are being blown into the tank from the pumps, which send the water back into the tank from the overflow boxes. How do I eliminate the air bubbles. I have tried to slow down the pumps by turning the union ball valves to close off the flow.

Any imput would be great!!!

These pumps are in a sump right?

You can add baffles in the sump after the pump and put a polishing sponge in there too.

There are a lot of people putting baffles in their sump these days.

Thanks for joining 3reef!

Also could be the pump is in need of a cleaning. Are you using a sump with a filter sponge?
