    Bio chamber defuser

    Evening all

    can I have some recommendations for diffusers for bio chambers please.

    Ive got one of them big weighted ones for a standby for the pond.
    I also have a couple of cheap ones which don’t sink and I’ve had to silicone them down, annoyingly one of them has come unstuck and now floats!!!!!

    Cheers

    Dave

    I just use these - one in each corner of the chamber - seem to work fine and sink - relatively low back pressure to.
