I got curious and checked the level on both and the on that breaks tanks is not level and the top appears to be "Torqued" or flexed so that it is not flat.
But not by much.
Is leveling the tank really that important or could something else be causing these blown tanks. The leaks are always around the top. I find it hard to beleve that two tanks were bad on their own and did not start leaking for a couple of months.
Unfortunately, sturdy furniture is not always good aquarium furniture. It's always best to use dedicated aquarium stands for your fish tanks. For a 29 gal
tank, at just over 7 lbs per gallon for fresh water ( 8 lbs for saltwater) , your "stand" will be holding over 200 lbs or more when you add in the weight of the tank and decor. Bedside tables are not designed to hold that kind of weight. The fact that the one is might just be luck more than anything else. That said, it is very important that the tank be on a solid enough surface to not twist ( as previously mentioned.) You can achieve this if the stand is not too warped by placing some styrofoam/ polystyrene sheeting under the tank to help absorb the different pressures the tank will be having. This can be purchased at your local Home Depot or Lowe's in the insulation department generally. I use 3/4" or 5/8" thick styro under all my smaller tanks under 50 gals. I double that thickness for larger tanks. The tank does not necessarily need to be flat level front to back but it needs to be not twisted. The problem when the tank is not level front to back is that water dripped onto the top edge will travel down to the lowest point then drop off the tank. I currently have 2 tanks that do this when the filter inside gets moved and the bubbles hit the top of the tank. I get a nice puddle of water on the floor in front of the tanks when this happens so I know to move the filter.
This may or may not have been your situation but something to keep in mind.
Hope this helps
