    Hi all,

    Well, what can I say? My son's TL-550 is now at the point where I can't do much more to it.

    So, I have now bought a 2nd hand 720l tank (1500l x 600w x 800h).
    I am going to collect it this weekend.

    A million things are racing through my mind as to what I want to do and how.

    First step... Finding the manpower to move the tank. The glass is 15mm thick!

    Does anyone have any suggestion on an insump skimmer for this setup?

    Was also thinking of going with 2x 250W Mh's with 20k bulbs. Would this be enough?

    I am busy contemplating the sump. The tank came with a 3 foot sump, but that will be way too small for a DSB, TS3 and return pump.

    Congrats dude. Now the fun begins!!

    am i right in saying that its HotDogs old tank?

    If so, you should look into changing the overflow - its so bulky and if you get a slimline one done by Idol Marine, you will gain more space (as well as more aesthetically pleasing)

    I was looking at buying it and got a quote from Adriaan for the overflow. R450 all in all :D

    Hi all,

    Well, the tank is now safely under my carport and I can start working on it...

    This is what the tank looks like now

    This is a drawing of the tank

    http://i872.photobucket.com/albums/ab287/johanpm/tank.jpg

    Right... Now I need ideas!
    I have a 3ft sump below the tank.

    What I was thinking...
    Close off holes D,E,F and G.
    Remove glass piece A and C (So basically same as B). This will give me surface skimming side to side.
    Use holes H, I and K as drain holes (down to sump)
    Use hole J as return back to tank. Pipe going over partition and into DT.

    What are your thoughts?

    hmmm johan was this over flow not designed to take a closed loop? it looks like it to me and personally i would keep those holes and put a four point closed loop in there so you dont have unsightly inetrnal pumps and its far safer for LS.

    congrats on getting it safely home

    Correct me if I'm wrong... For the CL -

    Water comes in from F and G
    Out through H and K to pumps
    Pumped back through I ???
    Split in to 4. Back into tank through D, E and the two holes on the other side of the tanks top bracing.

    Water to sump...
    Overflow B
    Out through J to sump
    Pumped back from sump into tank through which hole?

    Or - plan 2

    Water exits DT throug F, G and B
    Out H, I and K to sump
    from sump pumped back through J
    J split in 4. Pipes to D, E and 2 holes on other side of tank through bracing.

    This seems to make more sense. Only prob with this, you gonna need one helluva pump to pump back from sump.

    I saw this tank in person, those holes are meant for "overflow" (without it actually overflowing :lol: ) not a closed loop

    If you keep the overflow, you are going to have to modify the top to increase surface skimming. Hence I suggested just redoing the whole thing. You will gain that much more space in the DT....

    well then johan if i were you, id get the boys at idol marine to look at putting in a great overflow. So often the quality of the overflow leads to a well worked sump and that leads to an improvment of the water quality.

    Save the valuable real estate in tank, get a slim line over flow and have a system that surface skim:)
