    Hi all.
    I seem to be getting very fine bubbles from my sump into my tank.
    At which stage will this be a problem? When is too much fine bubbles a problem?

    it can be an irritant, but check your return pump is not sucking air

    will do no harm, but some plates can accumulate air under them which can cause that part to die.

    how quickly is the water moving through your sump. I would aim at a max of 4 times the tank volume per hour, currently mine is less than that !

    or your return pipe creates a vortex that sucks air down to create these bubbles.

    Thanx for the responses guys.
    I just got back from Lanzo.
    I have my flow the wrong way around and too strong. (I flow from tank, to DSB to sump (with skimmer and pump) back to tank)

    I'll change it tonight so that it flows tank to sump with skimmer to DSB back to tank.
    I'll drop the flow too.

    :)
