    So this afternoon after work my Tanks going in to Hellenic Glass Works in Benoni to be drilled.

    After that im building my overflow. 2cm from the top...is there a std size of dims that the overflow must be...or is it how u personally want it. Also can i use Perspex instead of glass?

    Are you having a Coast to Coast overflow or just an overflow box?

    no there really isnt a std dimension but obviosly you dont want it to small or to big coz u loose tank space...also make sure abt ur 2cm...check exactly where ur water level is before installing it or youll have trouble later...and perspex is fine no problem in that....just cover it in black..theres someting you get for this..not sure what its called...

    it's called ABS sheeting or if you have money to spend use perspex

    im not too worried about the looks of the overflow...but maybe black would work to conceal the uglies. lol

    you will get better surface skimming if you go coast to coast because the water wont be forced to just move through a small space(overflow)

    exactly and apparently coralline grows much faster on the sheeting than on the glass and its way cheaper compared to perspex

    I'm assuming the overflow is going to be inside the tank? Make sure it is big enough to fit a durso standpipe in there. And also big enough to get your hands in there should any fish or snails or hermits end up in there.

    Instead of having a box in the corner of the tank, you run a piece of glass along the entire length of the back of your tank or along the side of your tank, the glass sits at an angle near the top of the aquarium, you could also make it a box shape if you want.

    Wetty - the C2C (coast2coast) will have less of an impact on your tank water volume, than that of a corner overflow. Do you understand the concept of the coast2coast?
    It is literally just a piece of glass that has been siliconed in, RIGHT at the top, and JUST below where you want to have your water level. This strip of glass runs ALL the way from left of your tank, to right of your tank, on the rear pane of your tank's glass.... This glass strip for the overflow (C2C) is then siliconed in at an angle, when you view the C2C then from either left or right side of the tank, the shape it makes with your rear tank glass pane, is a V.....This glass strip should be wide enough to be siliconed BELOW the holes you are having drilled, and also cover the holes as well.... BUT not too wide that the water level is at or above your bracing...

    I see now. I think ill go with the plain overflow at this stage....and a C2C when I get a bigger tank.

    Thanks for the better explanation Jacques.

    Nothing wrong with a plain overflow Wetty, they work just as well. Be careful if you use perspex as I think you may need a special type of glue for it to stick to glass.
