    I used to have one on my last tank, it was full of pods and mysid shrimps but I did wonder how many survived the journey through the return pump to the display,

    If you want one solely for nutrient export it needs to be quite large to truly be effective, if you want it for bio diversity and pods to feed the display it's great.

    I've been doing some research and Doug, it seems that you're right that many don't survive the journey. Seems the best way is to have one next to the main display tank with the in and out tubes going over the top of both units using a pump.

    Looking at pictures, Fuzzy, one the same depth as the main tank and maybe a quarter of the width?

    In our RSM 350, we have a top up box in the sump on the top right 15658551551793933152841043954716.jpg 15658551931632752938987788041622.jpg 15658552252336654757657258841137.jpg which constantly gets blocked with salt residue at the pump end (the pipe outlet is tiny). We got fed up of cleaning it constantly as it's a pain to do, so we don't use it.

    Was thinking it could be used for something else....any ideas?

    So they don't survive going up the return pump but they do survive a pump from a dedicated fuge? Plenty seem to make it to my display alive. Best bet is to move the baffles in the sump to create a dedicated space. I'd move the ATO into the other side of the cabinet myself to give more room.

    Some must make it through the pump or people just wouldn’t bother but I suspect the mortality rate is very high.
    You don’t need a refugium to have pods, I have plenty in my tank and don’t have a fuge, I do feed plankton daily though, I think that probably helps.

    I think it's the skimmer that kills them?

    I'm not sure what the baffles are? Or the ATO !

    Refugium always after skimmer so. Bits of algae dont end up in skimmer pump.

    Baffles are the glass bits that separate the sections

    ATO is the auto top off that replaces evaporation

    Thank you! I think our baffles are glued, but we could move the reactor into the main section and see if we can put the ATO on the left and turn it into a refugium.

    Makes sense about the skimmer DOH!!!
