tiny bubbles from return pump outlet

[Teh Soon Seng]

is it normal to get tiny bubbles coming out from return pump outlet?

Those mircobubbles might be leak out from your skimmer outlet to your main tank via the return pump if it's newly installed. Let the skimmer set down for a couple days, the MB will gradually reduce to it's minimum.

if still have can try letting your water flow into a cup or container using a suction cup to hold onto the wall. have the cup a little above water. thats how mine managed to stop having micro bubble.

Can get these thick black sponge and place before the return pump,should decrease the microbubbles.

I just put a thin layer of filter white sponge directly at the return pump suction there. But must change when ever is dirty. (around once a week)
