    I have my old tank that I am going to use as a Refugium, can I suspend a smaller tank in it without support for it on the bottom, ie it will only be held in position by some glass attached to the bigger tank.

    The reason is that I will have about 25cm free space below the skimmer. So if I put the Skimmer inside a smaller tank and then suspend it in the bigger one I can make use of the space below it for LR. I want the incoming water to be skimmed first and allow any debris to settle before it goes to the LR. I don't have the space to put the smaller tank outside. I hope this makes sense.

    Sounds like a good idea to me, any settling chamber/fall out area is to be preferred above mechanical filtration. Removing after settling must be kept in mind as well.

    It looks to me that it can work.
    Just remember, rock and glass ... not good friends.(just stating the obvious)
    Good luck, keep us updated!!:)

    It will work. In fact I suspect your skimmers performance will increase with that box. Wastes are concentrated in a small area for the skimmer to remove. You will nedd to slow down the water going through this box, increasing the time the skimmer has to do its job.

    agree with Ivan.i think maybe fitting a ballvalve on your return will help reduce the flow,allowing more contact time with skimmer and water

    Thx, or you have a skimmer that can handle more water than the return water flow, so water flows into the box from the sump. The water from the skimmer is returned to the sump.

    Some thoughts: Why the chaeto and not a dsb?
    I suspect the first baffle is way too high. Personally i would lower it, to ensure more water reaches the first compartment. With reduced flow to improve skimmer efficiency, you will sacrifice the liverocks efficiency as a filter. (possibly becoming a nutrient trap) You will be amazed at how much crap is missed by a skimmer, and this will settle into the pores of your liverock. Maybe adding some pumps in there would help.
    Personally I would remove the liverock and use the chamber as a settlement area, then do liverock followed by a dsb or chaeto.
    Also, if drilling is an option, I would have the skimmer chamber overflow drilled and directed towards the beginning of the first bottom chamber.

    I was thinking of adding a DSB, I have on in the other sump. This will be the Middle Tank of 3. 1st tank is the display, 2nd will be this one and 3rd my existing sump that currently has my skimmer and dsb.

    Ok it has been running for 4 days, but it is not complete yet, still in test phase. Moved 2nd skimmer today and got the CaRx working, thought I would post a Pic.
    The 2nd mini tank in the tank seem to work very well as I have already seeing debris on the bottom, witch will be very easy to clean.

    Nice Thalion. Looking neat and professional

    I can see water coming in ; but cannot see the oveerflow.?

    See you experimenting with the skimmer necks of the am1000. I found that the only way i could get the longer one to work was to restrict the amount of air coming in.

    ? It is a mess at the moment.

    I removed a reducer in the pump so now I have more flow, so I had to extend the neck.

    The "over-flow" is on the right, the pipe above the pump.
    Had to do mods on the stand and got the height about an 3cm wrong, but it still works.
