How is it plumbed? You do not have any small diameter pipe, valves, fittings, sponges or other restrictions on the suction or intake side of the pump do you? Do you have a ball valve on the discharge side of the pump you can squeeze down slightly to see if the situation gets better? Generally adding a bit of head or restriction to the discharge side helps get rid of bubbles. If its a brand new system microbubbles are common and will usually go away with time.

do you have a protein skimmer in the sump with your return pump?

How is your sump configured? Do you have baffles between the pump and skimmer? How does the water in the sump look? take a flashlight and with the room lights off shine it through the sump front to back or side to side and see if the water appears cloudy or like it has glitter in it. This is evidence of microbubbles in the sump not caused by the return pump.
Again if its a new system this is normal and will go away or at least get better. |

Is it a submerged pump in their or an external pump in a drilled sump? Photos are needed, or specific descriptions of the equipment and configuration, if you want detailed guidance.

Another thing that can cause microbubbles is the return plumbing not properly sealed. It will allow air to be sucked in as the water passes to the discharge side.

Give it time, its a new system and bubbles are a normal part of starting up a new system. Nothing good happens quickly in this hobby, all good things take time.

Too much flow through the sump can be a problem as well. I had a large pump but my sump wasn't large enough to allow microbubbles to disapate, I gated it back and no problems.

What amount of microbubbles is normal? Should one expect the entire tank to not have a single microbubble?
