New tank micro bubbles

DawghuntR · Feb 28, 2020

Any idea on how to tune this thing! It's a hydor external skimmer tons of bubbles are coming from the outlet, I got the whole setup 2nd hand. I know now the skimmer shouldn't be in with the return but it is now. What can I do to stop the bubbles in my tank half are coming from the skimmer and half are coming from the refugium weir! Doing my head in... Tank is 1 week old. Can see bubbles in the dt only when you put a light above!
I know the back knob changes water level that works fine. Font know assume is for air but doesn't do anything it's just loose.

The skimmer will output water full of bubbles. This is why we have bubble traps in the sump before the return chamber. If you do not have a bubble trap then sometimes a sponge like material, like what BRS calls aquamesh can trap some.

Aquamesh Blue 3 - Medium

Progressive density mesh mechanical filtration system can be used as a system or separately. Aquamesh #3 is great for use after refugiums and before sensitive filtration equipment. Aquamesh #2 and #3 are the most common used. Dimensions:19.5" x 24" x 1.5" The Aquamesh progressive filter pads...

Seems by closing the valve on my return outlets I have fixed the issue! Skimmer still letting hubnlesnoit but by my return pump not pulling as hard the bubbles are popping before they get there!
