So are you saying these will spit bubbles frequently if it were on a wave maker?

taking notes here - great job! As a suggestion, I'd turn themj 90 degrees, so the elbow (grey one) on the output can be eliminated for greater flow rate.

reefdood, there's a possibility, id have to hook it up to one to confirm it.

Bennyinca, Ya you could but you'd still be using an elbow to connect to the intake of the pump so you're losing pressure somewhere no matter what.

I disagree with this statement somewhat because if you use large enough tubing on the intake side, this effect should become negligible... I think.

nice work! If you haven't sealed the pumps yet, have you tried filling the acrylic box with water to see if it cuts the bubbles? Most likely it is just a sealing issue around the tubes...

The air is mixing before the intake and i think its because of the threaded connection. Ill have to do more work on it to see. I need to just modify an existing U tube if i can find a place that just sells those.

**UPDATE**

I finally got rid of the micros and i wanted to update anyone that is doing this diy. In the beginning i was using all 3/4" pvc and i think that was the problem with the micros. The problem was i used a 3/4" to 1/2" barb right before the powerhead with flexible tubing. After reading about the flow rate on the mj and of 3/4" tubing i switch and went with a 1/2" to 1/2" barb connector to compress the water and remove the micros. It worked like a charm and no micros to speak of. Hope that helps anyone trying this.

Great help . I have to build one ! Anybody want some powerheads .LOL

 

[Dizzyswimmer]

Yep, send the powerheads to me !!!

Right I know... I just was bumping it up so that it would show up in my subscribed threads... I kept having to tell it to go to the beginning before I could see the thread, and it took forever

 

[JOSEPHLB]

Pretty neat idea.

Still curious if you could use the venturi connection to initially prime the u-tubes.
