Microbubbles and cloudy water, help please

[texanjordan]

What I plan on doing is putting the 3/4 barb on the return pump and adding 3/4 tubing. the 3/4 inch tubing fits very snugly inside 1'' tubing and that is how I am planing on connecting them. If you have a better idea on how to connect 3/4 inch tubing to 1'' tubing I would be very interested.

I made some changes yesterday, I changed the plumbing on my return line to soft plumbing to see if that fixed the issue with the micro bubbles, it did not. I was able to determine that the bubbles were coming from my brand new Mag Drive pump. I pulled the pump and replaced it with my old much weaker pump, and surprise, no bubbles! I need to call danner and try and figure out what is wrong with the pump, and why it is shooting constant bursts of micro bubbles.

I added some seachem water clearing solution to my tank, and over the last 36 hours my tank has cleared up considerably, almost crystal clear.

The only way a pump can blow bubbles is if it is sucking air. Is your Mag submerged? If so, it ain't the problem.

A venturi effect will happen with a much stronger pump. So it might still be your plumbing.

The pump was completely submerged. I used the same plumbing with my old pump, and there are zero air bubbles. I called bulk reef supply where I got the pump and they told me it sounds like an issue with the pump and to call danner directly for trouble shooting. What do you mean by the venturi effect? Im familiar with venturi de watering pumps from my cutter days in the coast guard, but not when it comes to plumbing lol.
