I was thinking of double stacking my two tanks......135 & 120
6ft long tanks. i need to get the one out of my girls room to make room for new furniture. I was thinking of using cinder blocks and just making a frame with the 2x4's having maybe 4 or 5 going the width of the tanks, maybe more, sitting on the concrete blocks. Do you think the top one will be an issue with no center support and what about the weight on the cinder blocks?

I don't want to spend a bunch on wood. I already have enough 2x4's to do something like this, just would have to buy the concrete blocks. Never really tried my wood working skills, but it seems like this would be pretty easy.

What are yall's thoughts?

From what I'm interpretting you are planning to have the 1st tank on the floor? I'm not sure how you will suspend a both tanks on cinderblocks. That aside, I'm concerned with a few things here.

1. Placing Just 2x4's under a piece of glass could lead to problems as there is a natrual arch/bend in this type of wood and that could bend the tank.
- Consider getting some 1" foam insulation to put between the 2x4's and the glass this, in my experience, will deal with this problem

2. I don't see a lot of thoughts to keep the tank from "swaying". You are going to have at least 1200lbs of water and glass sitting on a couple of 2x4's that, from my interpretation will not be anchored to the cinderblocks. I would worry about the tank if someone fell, tripped, bumped heaviliy into it.
- Without additional information I can't really say I like this for stacking tanks. just an opinion mind you.

It's very possible that there is simply not enough information here yet. I don't want to seem like i'm bashing your idea either just some observations to be considered

This is not an exact answer you are looking for but. . . my 55G is sitting on 6 concrete blocks two on the left two on the right and two under the center of the tank. I have two pieces of 2X6 laying on top of the blocks unsecured. I then went to a fabric store and purchased velcro and fabric. I stuck the velcro all the way around the front and sides of the bottom of the tank to the black plastic. I then took my nice black fabric "kind of like dickies material" and put velcro on the top edge of that and stuck it to the velcro on the tank. No one believes this is what is holding my tank when they see it. It looks like something you would buy as a stand. This was MUCH cheaper then buying a stand. This stand is very sturdy much better then any thing you can buy ready made. There is 0 movement when working on the tank. I honestly do not think you could knock it over if you tried. The weight of the tank makes it stable and its sitting on carpet so it is kind of settled in.
I understand you are working with much larger tanks and raising them higher off of the ground but I figured this info may help you out.
