    I have this cube thats been cycling for a week. Problem is micro bubbles from the skimmer outlet. Its a Reef octopus 160x and is completely ruining the display with all the micro bubbles its creating from the outlet. I have tried full wet and full dry skimming and it doesnt make a difference. I added some filter mat in the return chamber which helped a bit but the problem isnt going away. Any ideas?

    sitting with the exact same situation here, but what makes mine worse is, that its a HOB. So there's pretty much nothing i can do to make it stop. :005:

    Hope you come right!

    Will be interesting to see some of the sugestions that might come out!

    Your skimmer might be in too shallow water...also what you can do is add a 90deg elbow to the outlet and make it face down

    I had the same problem with my HOB. I solved it by closing the airline a little and the bubbles are gone. I hope this helps?

    Read this on reefcentral:

    It is normal for new skimmers to release microbubbles from the output. As the skimmer breaks in and the oils dissapate you will notice less and less exiting. When the skimmer is fully broken in you will no longer have this issue.

    Do you have a proper bubble trap after the skimmer? Over-Under-Over baffles? I know you have space constraints but this is especially important if your skimmer is next to the return chamber.

    put a packet over the skimmer outlet and make a cut in the packet to allow the water to escape all bubbles wikl get traped in packet

    Put a packet AKA PLastic, {what the stores charge you for to put your groceries in while you take it to your car:tt2:}, over the outlet of the skimmer. make a hole in the packet so that the water can come out, ALL the bubbles will get trapped in the packet and your issue is resolved:thumbup:

    I added a Dymax bubble reducer. Its just a filter sock that sits over the skimmer outlet. No more issues

    Hay bud I know you fixed the problem so to say but did you try adding more air to the skimmer eg letting it suck more are what I have noticed with my deltc is that if I close the air inlet to much it make a lot of mico bubbles just an idea

    What is the water height difference between skimmer chamber and return pump.

    If more that 30mm then the waterfall will pull down the bubbles very far down, into the return pump inlet. Also add a 90 degree bend on the return pump inlet, facing down, with a max 5mm clearance. So that the pump must suck water from the lowest point possible. That would give the bubbles around the pump change to get out. Also position the pump so that the intake is as far away as possible from the waterfall.
