not a big deal , but the ocd in me wants to figure out why bubbles are coming out of one jet but not the other. trying to stop the bubbles could it be because i drilled a siphon too high on the right left one? its about an inch above the water line. both lines are connected to the same 1" vinyl tube with a tee barb coming from the return pump , and the return jet has a ball valve on it.
