What's up richie?? I just wanted to ask you a question, I can't stop these ******* micro bubbles coming out of the return!! I tried almost everything (that I know of lol) and hasn't helped.. I changed the return line, I changed and tightened all the other lines I just can't figure it out, if you have some other insight on what you may think it is please let me know thanks, hope all is well and I'll talk to you soon!!
