Warren Posted December 6, 2002 Report Share Posted December 6, 2002 I've updated this article recently. Anyone who has used it and found it a little confusing should now find the formulas work. I had accidentally stuffed up the ^2 and ^3 and ^4's in a few places. The excel version has always been ok. Download the calculator and use it to check your tanks for safety. You might be surprised at how good some tanks are, - you also might not. Quote Link to comment Share on other sites More sharing options...

gerald Posted March 15, 2007 Report Share Posted March 15, 2007 :bounce: Warren the formula shows a sample of a tank The red letters are meansures to fill it out According to your formula Height 1000mm Height 1000mm Length 3000mm Width 3000mm Safety 3.8 Thickness 27.06mm = glass thickness all sides Safety 3.799750573 Thickness 27.06 mm In conclusion H=1000 x L=3000 x 3000 W =27.06 mm all glass sides Are these meansures ok ? tks Quote Link to comment Share on other sites More sharing options...
Warren Posted March 15, 2007 Author Report Share Posted March 15, 2007 Yes, but it's a very big tank, approx 9000L. The bottom glass will need to be approx 38mm and the base will need to be solid concrete with a surface prep to make it level withing ±0.1mm. Alternatively, a concrete bottom with no glass and use glass only for the sides. You may also want to look a acrylic side panels at this size as they flex a lot more than glass and will help take up any errors in construction. The thicker glass gets, the less forgiving it is to assembly errors. Quote Link to comment Share on other sites More sharing options...
gerald Posted March 15, 2007 Report Share Posted March 15, 2007 :bounce: Thanks for your reply In my mind I want to build a fish tank for a bamboo shark 8' length x 4' height x 4' width ( 2440 mm x 1220 mm x 1220mm ) = glass thickness 33.91 mm All concrete and the front view in glass, that's I’m trying to get prices between temperate glass and acrylic sheets 8’ x 4’, but acrylic cost a lot of money, and my pocket only can support glass. Do you have any suggestion for this proyect ? Let me know and again tks a lot. I’m gratefull with your help Quote Link to comment Share on other sites More sharing options...
