Drain air bubbles

[Bill Urbanski]

Ok so I have a bashsea sump. The drain lines are making one heck of a lot of bubbles. How can I stop that? So the drain lines enter a compartment then go up over filter socks then to the refugium. What can I put on the drain lines as they enter the sump to stop the bubbles?
