    i have a 4 foot tank with the overflow on the rhs,inside, of the tank. my overflow height is too low in the sense that the water height of the tank is too low and when my hood is on u can see the gap between water height and hood.

    how do i increase the water height without doing another overflow ???

    Why not just silicone on thin strips of glass to make overflow a bit higher?

    Alternatively you can make it appear higher by using a much stronger return pump, or lowering the sides of your canopy.

    If you use glass use the same thickness glass as the rest of your tank, If the tank is 10mm you cant use 2mm glass, perspex should work will silicone stick to it ?

    Just switch off your return pump for a while, dry the insides of the overflow box and stick glass/perspex in place on inside.

    Leave for and hour at least before switching on return pump. Preferably 2 to 4 hours. Any thickness glass would work. I would stay away from perspex though. Silicon does not stick to perspex very well.

    Yip raise the overflow slightly with glass, silicone will stick to perspex for awhile but will eventually let go.

    As long as there is no pressure on the perspex it will be ok. I suppose if he really wanted he could try perspex. There won't be a large amount of pressure on the perspex and if it does give way it won't affect much besides the water level.

    Afsal,

    Don't bond Acrylic to Glass with silicone. Rather fabricate a detachable wall from perspex, then hang it on the glass. See pic. The teeth are optional.

    The pieces of perspex can be bonded with Methylene Chloride, available at the place where you get your perspex. The bond is extremely strong and should last forever as it fuses the perspex together.
