    Good afternoon clever people,

    I have a question regarding my NW 150 External Reef Octopus skimmer. I recently bought a new one and added it to my 600 liter system. I am running a Diablo DC 5500 on the return and then split it to my skimmer back into the sump

    Now my question is, what should the flow rate be through the skimmer because I am not entirely sure the skimmer is skimming correctly. I am only getting small bubbles that does not even go into the cup. Water level is just under the skimmer cup. Is this correct or am I doing something wrong. Any suggestions. Thanks a lot everyone :)

    What pump is running on the skimmer itself?

    Height of skimmer in the water? Sometimes if its mounted too deep the pump cannot make enough fine bubbles

    i think the key word in the first post would be External.. so it would not be submerged..

    Thats correct thanks Nur. ;)

    The water level in the sump is at 150mm if that helps

    Thanks

    check the impeller in the OTP pump if there is dirt on the needle it wont make bubbles.

    Should there be high flow through the skimmer? At the moment there is not a lot of flow but I did try it both ways

    Not sure. I experience my Skimmer not making lekker bubble when impeller was dirty and once when a fly got stuck in my air intake..
