cpr bak pak with large air bubbles. please help.
i have this skimmer and have had it running for a few months on a used tank that i bought used. i understand how to adjust the air intake and im sure ive got that part down.
im getting tons of large bubbles from the outlet of the skimmer. they are not visible inside the chamber so they must be coming from the outlet pipe. i was wondering what could be cuasing this or if there is a piece missing or something? thanks
