Stand and Tank Stability/Safety???

[wheresknott]

So I bought a 40G breeder and Stand from small pet store (unfortunately no returns to this store). When I finally got around to setting it up I found that the tank is not totally straight. I found this out when I was trying to place it on the stand. Its one of those stands that has the hollow center. When I went to place the tank on the stand two corners (diagonal from each other) seemed to meet up with the corner of the stand and the other two didn't seem to make it as far. I would then go under the stand and look up at the tank and try to adjust it as best I could to make sure that they two sides that didn't meet up with the corners was supported as best as I could make it. I literally spent 1 hour adjusting from the top and then going underneath to adjust again.... Anyway I just wanted to get your thoughts on support of the tank. Also, how much of the tank has to be sitting on the stand to make is solid.... Attaches are a couple pics..... One of these shows a good corner vs a not so good corner. I also included a couple pics from underneath.

Thanks in advance.

those particle board stands don't give much of a lip to sit on , I can see your concern with this , as long as a good portion of the plastic base frame is in contact with the stand it should be fine once you add water the tank wont move as the weight will keep it in place ,

But if you don't feel comfortable you could always add a plywood base to give you that little extra support ,

looking at your picts that is exactly how that stand was designed to hold the tank the base frame of the tank just rests on the lip of the stand (just be sure it is centered)
once it is full of water it wont move as the weight of the water is what keeps it in place.

here's a good example I didn't feel comfortable how this tank sat on the stand so I added a piece of plywood for more surface area contact
