Good job. With a 2x8 beam doubled like that supported with 2 jack posts you are golden.
Should be able to park an elephant up there

Make sure your jack posts are screwed in and you are good to go. A structural engineer would cringe... but that'll hold the weight for sure.

Thanks guys. I know it's not pretty or spot on to an engineer but its the best I could come up with
 all I need it to do is help hold the tank up.

I was going to do the same as you when I had my 125g
A builder aquaintance suggested a 1/4" steel plate of 6x6" or larger under the jack post The wood you have under it may split and could be a bit larger to prevent the concrete from cracking (it is a concrete floor, ya?) I also talked to an engineer. Because of the cost of liability I didn't pay him for his services. He told me he entered my flooring and weight specs into his formula and told me that, if I were to pay him, he would suggest the above idea as a minimum, but because I wasn't paying him, he wouldn't be legally allowed to tell me that  The rest looks great. All I'd add to it is some cross bracing between the new support joists to prevent twisting Last edited by gregzz4; 07-20-2013 at 08:35 PM.
