i have started building this stand using 2x4's. im concerned that it wont hold. any suggestions? its going to have two 75g at the bottom and a 8 footer on top.
thats what i had originaly intended on doing but i let my dad convince me to just stick with 2x4's. he doesnt understand how heavy these fishtanks are once they are full of water. since i have alot of 2x4's could i just use 2 for each post?
yea just screw to togeather its just as strong thats what i would reccomend. run some along the bottom as well so the legs bow move as the tanks fill and sit. as well as braces along the top. jmo. make it as sturdy as possible so that way you know its not going to break..
I checked out the gallons and the weight and you will have 2700 lbs in just water. That is alot for a 2x4 structure. you may have to separate the tanks. if you put it on anything other than a basement or ground floor room you my exceed the structural integrity of the floor also.
i would also use a 2x4 reinforcement brace across the middle of each bottom tank and three across the top tank. 4x4 or 2x 2x4 in the middle of the top tank. for the 6 posts i would make it 4x4 or 2x 2x4. Overbuilding of this will be a necessity.
