Micro Bubbles

[Rukus]

Hey guys, well im having a bit of a problem with micro bubbles, im not sure where they are coming from. I designed my sump as to hopefully not have this problem, but it still seems like im getting some.

Is it possible I may have a suction on my return line? if so whats the easiest way to I go about making sure I dont?

take a good light put it above your sump
you wotn realize how many bubbles you actually have untill you have a light a look closly

I had a microbubble problem with my closed loop once. All that needed to be done was add some extra teflon tape around the threads on the pvc fittings and tighten them up using an adjustable wrench. Before I did this, I was getting air sucked through the intake on my pump.
