That's along the lines of what I was thinking. It seemed like that pump was having a really hard time getting the air pockets out of the lines. I had to rock the case back and forth pretty rough to get the tubing to even completely fill with water. I know this isn't the best way to determine flow rate ( I don't have an inline flowmeter for my 1/2" tubing yet) but just looking in my res (tank-o-matic plug-on), there is so much suction from the pump it looks like a whirlpool in there. Whereas before moving to half inch, the suction from the pump barely caused a ripple in the water. So I figure there has to be more flow than before, or do you think that there is just less resistance and my velocity went to crap. I'm leaning towards getting a Danner mag3. Does this sound like a good idea?
