Micro bubble problem

[tomowilson]

My tank is experiencing micro bubble problem for the past 2-3 weeks since I changed my return pump to Aquabee 3000. Previously, I was using Rio 10HF without micro bubble problem. I am using mainly rubber hoses.

Any suggestion?

connection between the rubber hose and fittings might be letting air in. try cutting off the part where it used to connect to the Rio to make a tighter fit with the new pump.

I tried doing that by cutting off the part which was connected to Rio but the problem is still there. I will change the whole rubber hose tmr since it starting to harden.

Cool. The new pump may have residual air inside its housing, try to let all trapped air out of the housing.
