Bubbles from the return

[poonaka]

I built a SM 100 and put it above my display. The return from the SM 100 goes directly to the display. Unfortunately I'm getting a ton of bubbles from it. Any tips on how to get rid of the bubbles?

Attache a "T" to the drain, where one half of the T goes up to the air, and the other half goes into the tank. Also, different flow amounts will make a big difference (including more flow). Play around with the T and flow amounts, and you should be able to find a no-bubble setting. Last resort is to use a larger bulkead.

Does the half that goes up into the air need to be higher than the scrubber water line?

No, just into the air.
