    ja sorry, it is A2 drawings, so when I plot them they will be more detailed, thanx for the upload... Let me explain, it is a 800Lg x 500Wd x 500h 6mm glass, got an overflow at the back, with two 1" holes in the bottom for gravity feed, got a 1" at the back for a pipe to come through so I can return water again, sump starts on the left with skimmer, then dsb the return pump, is it nesecary for all the bubble traps? i kinda like it tho... Thanx guys, Im such a noob...lol

    if it works for you its fine but here is the calculations

    Aquarium glass calculatorTank Water Height (H) (mm):470Tank Length (L) (mm):800Tank Width (W) (mm):500Recommended Safety factor (Sf) :3.8 Recommended Side Glass Thickness at Sf :7.3Maximum Deflection of Glass (mm):0.36 Recommended Bottom Glass Thickness at Sf :10.3Maximum Deflection of Glass (mm):0.27 If side glass thickness is changed to (mm):6then actual safety factor =2.6 If bottom glass thickness is changed to (mm):6then actual safety factor =1.3Aquarium glass calculatorTank Water Height (H) (mm):470Tank Length (L) (mm):800Tank Width (W) (mm):500Recommended Safety factor (Sf) :3.8 Recommended Side Glass Thickness at Sf :7.3Maximum Deflection of Glass (mm):0.36 Recommended Bottom Glass Thickness at Sf :10.3Maximum Deflection of Glass (mm):0.27 If side glass thickness is changed to (mm):12.5then actual safety factor =11.1 If bottom glass thickness is changed to (mm):20then actual safety factor =14.3

    Mr G,

    I am currently sitting in Australia on business, I am modelling a coal mine flow scenario on my computer and the run time for each scenario is about 2 hours ..... needless to say i am somewhat bored watching a status bar...... My boredom, your gain.... so i started some designs for your tank for you to consider

    consider the following as a base case (assuming your dimensions are still 800 x 500 x 500mm

    [​IMG]

    the central over low has dimensions of 150 x 200 x 470

    Also just a point on the glass thickness ..... using 6mm glass indicates a safety factor of 2.4 for the sides and 1.2 for the base, we generally reccommend a safety factor of about 3.8 which indicates a required thickness of 8mm (calc says 7.5mm but 8mm is the closest) for the sides and 10mm (clac says 10.6,, but IMO 12mm would be an overkill) for the base. If you have children or the tank is likely to be bumped or if the tank is not exactly level, 6mm may be inviting disaster

    I have also just started a thread in the beginners section on the various types of overflows you may want to consider while designing your tank, it will depend greatly on where you want the tank to be located as to which option is best for you, have a look here
