Only takes a fraction of a inch worth of difference in the floor making it uneven, this will put stress on the aquarium and will more then likely
cause it to break somewhere, could be the frame that cracks, or you could lose a entire pane of glass.
It does happen.
precaution you can take, lay down something thick and soft under the aquarium.
No, not your comforter from your bed. I suggest insulation board that is used on the exterior of
buildings/houses.
a 4x8 sheet that is 1/2" thick can be had for $8 at Home Depot.
Okay, I've got a couple of questions. I can understand the wooden porch causing unevenness, but a solid concrete floor? As long as the floor was built even, how can it cause a stress fracture on the tank?
Also, if I can't do the water test on concrete or the wooden porch, where else would you suggest doing it? The only other place I can think of is the garage which is concrete as well but would be more uneven than the concrete/carpet floor I have it in now.
And lastly, is this the insulation board you are referring to: http://www.homedepot.com/h_d1/N-5yc...splay?langId=-1&storeId=10051&catalogId=10053.
Your help is greatly appreciated, thanks.
