TheyCallMeMr.703 February 1, 2014 Share February 1, 2014 (edited) I just got done building my stand, minus the skin. I'm curious whether it is strong enough for a 90g. I built it for a 75, but would 90 be pushing it?? I have a chance to upgrade here, just want to make sure my stand is able to support the weight... The top and bottom ''frame'' is built with 2x6's, and the rest is 2x4's. Is this strong enough??? The frame top and bottom ''frame'', are also pressure treated for good measure as they will be getting wet at one point, and plan on this stand being used for Many Years to come... So... Is it strong enough??? Here is a blue-print. I took out all middle braces, minus one to help keep its shape.... As this is a glass tank, and only needs to be supported around the edges, I felt as tho' this would be a good call. Quick Pic. of The Stand, still need to add One Middle, support brace.

DaveS February 1, 2014 Share February 1, 2014 Should be fine. Will probably hold twice what you need for a 90. Link to comment Share on other sites More sharing options...
TheyCallMeMr.703 February 1, 2014 Author Share February 1, 2014 That's what I'm hoping.. was the plan, should '' Hold a Tank ''. but just one of those moments where, you know. "' just need to hear it from others as well''.lol Link to comment Share on other sites More sharing options...
Mattiejay6 February 1, 2014 Share February 1, 2014 Easily hold a 90.. Link to comment Share on other sites More sharing options...
smallreef February 1, 2014 Share February 1, 2014 (edited) I'm assuming that is sun wood and not outdoor pressure treated....make sure you seal every inch of it though....the 'treatment'' is a chemical....

zygote2k February 1, 2014 Share February 1, 2014 take shelter under that colossus next time an earthquake rolls through.... overbuilt and can probably literally hold a car. Link to comment Share on other sites More sharing options...
smallreef February 1, 2014 Share February 1, 2014 Lol Rob...that ain't holding my car...but it will def. hold a 90g tank... Link to comment Share on other sites More sharing options...
zygote2k February 1, 2014 Share February 1, 2014 Lol Rob...that ain't holding my car...but it will def. hold a 90g tank... Where's Origami or one of those tech types that hang out here? I believe that it will indeed hold a car if the car were placed onto the stand and not moved laterally. Each corner has 3) 2x4's vertical and reinforced with cross bracing, it'll probably hold more than 2000#. Link to comment Share on other sites More sharing options...
smallreef February 1, 2014 Share February 1, 2014 Okay rob....you have to try it now...I need to see it in real life,lol Link to comment Share on other sites More sharing options...
paul b February 1, 2014 Share February 1, 2014 You don't need a center brace for a 90 gallon tank. It looks good, I assume you used deck screws as sheetrock screws will rot in no time. Link to comment Share on other sites More sharing options...
Origami February 1, 2014 Share February 1, 2014 I can run a beam deflection and compression analysis, but I believe that it would easily hold a tank - the Army kind. As long as it was balanced and didn't fold. Seal the PT lumber. Kim is right that the chemicals that they use today include a lot of copper. I ran into some problems recently when I left a board across the top of my sump (to work on some stuff overhead) and forgot about it. Some salt creep and a couple of distressed acropora alerted me to the problem. Sent from my LG-V510 using Tapatalk Link to comment Share on other sites More sharing options...
TheyCallMeMr.703 February 1, 2014 Author Share February 1, 2014 Yessir, used Rust'Oleoem Screws. And also, Did not know about the severity to how bad the treatment process was. I planned on sealing it all very thoroughly, but did not even have a clue about that, will make sure to give it that, ''Extra Coat''. Thanks Guys.

Origami February 1, 2014 Share February 1, 2014 They used to use an arsenic-based compound. But, because of concerns that the PT wood was being used in so many kids playground sets, the industry moved to a copper-based compound. Either way, the compound doesn't belong in your tank. But keeping it out is not difficult if you just take precautions. Link to comment Share on other sites More sharing options...

But keeping it out is not difficult if you just take precautions. Thats why they don't make toothpicks out of preasure treated wood. Also remember that the preasure treatment just makes the wood less prone to rot and termites, Preasure treated wood is cheap pine and it warps just like any cheap pine. But it should be fine for what you are doing. Link to comment Share on other sites More sharing options...

dante411x February 4, 2014 Share February 4, 2014 take shelter under that colossus next time an earthquake rolls through.... overbuilt and can probably literally hold a car. Something just a little more overbuilt than this is holding my 220. And it could definitely hold my car.

Origami February 4, 2014 Share February 4, 2014 Ran the beam calculation just for grins. Predicted deflection on the top beam is .0035 inches (about the thickness of a piece of paper). Assuming a conservative max deflection of 1/8", that stand could hold nearly 38,000 pounds. Link to comment Share on other sites More sharing options...

OcalaReefGirl February 5, 2014 Share February 5, 2014 Lol, I guess it will be good for a 90 gallon. Nice to know that we have enough nerds together to sort that kinda stuff out!
