    Hi all,

    I need your input on the following:

    Tank will be 2000 x 1000 x 750 (water level at 700).
    I will be running 2 Tunze 6105's in the tank, but would like to add a Tunze wave box as well. I would like to create a wave effect in the tank.

    The tank will be braced at the top.

    The question would be on glass thickness, can I use 12mm or should I use 15mm or even thicker glass? I need to make sure the glass can handle the stress of the wave effect.

    Properly braced 12mm should be fine but 15mm is always better. I would drop your water level another 3cm personally, it will give you more scope for the occilation motion along the top as the "wave" can get quite high, also remember that overflows are best placed centre back when a wavebox is used or otherwise you will have a noisy tank as the water splashes over a side fitted overflow

    Thanks Les,

    Will drop the water level.
    The plan for the overflow is at the back c2c with 4 holes in the base.
    2 will be used for overflow to sump, 1 will be used for return and the other for electronics for pumps and wave box.

    The top will have a wooden frame around to hide the bracing. It will also hide the return line, that will put water back in front of the tank.

    Lights will be Reef Inmates SPS extreme with 3 250w MH and T5's. The lights will be hung from the ceiling.

    One more important thing is that the stand will be an over kill to make sure it can take the hammering of the waves and massive water weight.

    The nice thing is that the tank will be a room devider, so the sump will be accessable from both sides!

    Eish, I can feel the pain of that electricity bill comming on. Sounds like a cool set-up you planning.

    R600 just for the light unit or to run the tank?
    Why not take the plunge and go LED,sure it will save in the long run

    Hello Icornelius

    I will be sending you the required formula that they recommend (tank build)to run a wave box without hassles late.r (pm)
    If you could go away from a c2c overflow it would be a better bet as maximum effect is achieved by having a central overflow and it can be quite long. 100mm height should be considered as once the sweet spot is found your wave can be considerable depending on rock placements. A 12mm build should suffice for that size tank.

    R600 for everything.

    Wanted to go LED, but it will be a very expensive mistake if I don't get it right (DIY). Also buying a LED unit will cost 3 x the price of the Reef Inmates unit.

    I did some more reading last night and see that you need to run a center overflow.
    The thing that worries me is because my overflow will be on one of the sides the wave will make allot of noise. On the Tunze web site it states that the best place for the overflow will be in the center of the tank since that is the point where the water level will be constant.

    Any other ideas?

    Hello Icornelious please find link for Timoshenko Formula for tank Build

    http://de.saint-gobain-glass.com



    You could also get a wave motion by syncronising all your pumps via the controller to pulse at a very fast frequency say anything between .05 to1.2 sec from 30% to 100%

    The problem is that the formula is in German
