Sump help please?

[cav~firez22]

Hi everyone,

I just bought a 135 Gallon Tank, stand canopy, sump & pump system.

I am having issues with my sump, as i am new to this setup.

Here is a pic of the sump, running.


My issue is micro bubbles. i think

My tank is just clouded with them. its not crystal clear at all.
I have the returns backed to around half, and there are still micro bubbles going in to the 3rd chamber of the sump.


Any input on how to have the sump setup would be great... ie. filter media.
