    overhead fuge question

    I have a spare 10g tank and a maxi 1200 gathering dust and am going to try to put together a fuge for my 75g.

    I can put the 10g behind and above the 75g (through a wall to furnace room).

    Using rc's calc. it says I can expect a flow rate of about 138gph. My understanding is a flowthrough rate of around 5X through a fuge is good.

    If I use a valve to reduce flow rate, is it better to just restrict the flow or to divert the flow (some sort of T) back to the tank?

    Any other thoughts or ideas would be appreciated.

    I have a 10g refuge above my tank at home and I'm using a maxi-jet 1200.
    I use a valve on the line to restrict the flow. This way, as the line gets coated on the inside, I can open the valve more to allow more flow. And I can shut it off completely if I need to.
    My current valve is a c-clamp...

    How much lift from the maxi to the refuge?

    you have to drill the tank for a return. drill 2 would be better.[safer]

    I had the 10g tank drilled, using a 1.25 inch pvc pipe that overlows back into the main tank.
    I'll be removing the maxi-jet soon and cuting the main return line from the tank and splitting it to feed the refuge. Don't like the extra maxi-jet in the main tank. I did try putting the maxi-jet in the sump first, but it was too much lift for it.
    I will take a picture and post it later this afternoon if you like.

    any suggestion on return line size. Thats a good idea JR, should both holes be same size? I assume you recoment this incase of blockage?

    Drilling two overflows is always safer...both would be the same size. The plumbing from the refuge from the overflow should be larger than the overflow hole itself.
    I use a 1/2 return line. I find it's plenty.

    IMO if you drill for a 1.5 inch bulkhead as close to the top of the refuge as possible and use a 1.5 inch screen like Ivan sells your chances of having a blockage are slim to non existing. If you continue the drain line back to the tank with 1.5 inch piping you will be fine. Again IMO there is nothing that can get through the screen that will plug the 1.5 inch drain.

    Holy Sh*t, boy does tempered glass ever make a loud bang when you try to cut it! . mg3:

    At least I think it was tempered. When it broke it shattered into small pieces.

    Looks like i'm going with rubbermade :biggrinbo
