Another bubble post

[matty]

Ok, I hope someone can solve this air bubble mystery!

We set up our 120 gallon tank last weekend. I have a mag 9.5 that was originally set up in line. We were getting tons of micro bubbles, a non stop supply coming from the return. Could not find any leaks and had plenty of water in the sump. I removed the pump from inline and placed in the sump which alleviated 95% of the microbubbles.

Now, instead of these tiny bubbles, every 6-7 seconds we can 4-5 larger air bubbles coming from the return. Any thoughts?

The current setup is a mag in the sump to a flap style chck valve, theh a ball lvalve and flex hose to the bulkhead leading to the return. Please help.

Thank you.

Make sure your pump is completely under water the entire time, I'd say at least 4 to 6 inches above the inlet otherwise it can suck in air. If your still getting air, run a temporary hose to the main display from the pump, you can get one at your local home center, just to eliminate all of the plumbing.
