Folks,
I have been fighting periodic micro bubbles in my tank. I have ruled out the skimmer and there are no bubbles going into the return section of my sump. Its not constant, but every 5 seconds or so I get a burst of bubbles from both returns. So before I rip out all the PVC I would like to test a new pump. Also, I did not have any problems until I hard plumbed the returns. I have checked all the joints and there is no salt creep on anything. It could be a pin hole, but I would like to rule out the pump as its easier.
If anyone has a 3/4 inch output punt between 700 and 900 GPH that I could borrow for a few days I would greatly appreciate it. I am in Cedar Park so the closer the better!
Thanks in advance.
James
