Need Help with DIY Stand for 120 gallon

[spiderman097]

I ran into some trouble with a DiY stand guide. The 2 guide bars in the back are blocking my rear overflows. I need to chop them or remove them completely in order for my tank to work. But this could be a really bad idea. I would have to reinforce around the corners definitely. But the bottom line is, would is still be stable? Any advice is greatly appreciated. I've included some pictures.

I will be removing 2 of the rear green blocks.

I don't have a DIY stand but on my stand, they used 2 pieces of 3/4" plywood for the sides and the back section. When I bought my tank from another member, the stand was messed up on one end so I had to replace the whole end. Here are the before and after pics.

I used liquid nail and screws to hold the two pieces of plywood together and then to be on the safe side, I added the 2x4 (going diagonal) to give it extra support. I hope this will help you.

To the OP...the way that is framed gives very little support. All of the wight is supported by the screws and glue (assuming you used glue). Here is how I would fix it.

Using 3/4" plywood I wood wrap the entire stand. The plywood needs to run to the base of the cabinet or the floor and the top needs to rest on the top of the plywood sides. This will transfer all the weight through the plywood to the floor. Then you can remove that 2" x 4".

The 1.5" of plywood runs from the floor all the way up to the underside of the tank. Its the identical way it came from the factory except its plywood instead of that compressed crap. I also added 2x4's vertically to give extra support but you can't see it in the pic. I had a carpenter look at it and he says it looks good.

Actually, according to your drawing, you have to many 2x4's in place. I got a DIY stand with my 93cube that was built exactly the same way. I cut out the inside 2x4's completely and it held that tank without any issues at all. In the case of a 120, because of span, I would put a 2x4 in the middle of the back. Then if you wrap it in 3/4" plywood....you will never have an issue.

You could take out that one green board that is in the way and attach the two purple ones in that corner with pocket screws. The pocket jig is only about $35 at Lowe's or Home Depot. At least it was a couple of years ago when I bought mine.

Remove the 2x4 that's in your way, it's structurally useless the way it's installed anyway. After you remove it, cut it shorter so that it fits between the rear top and bottom rails, and screw it in place. Done.
