I have built a couple of 20 gallon tanks but now im second guessing the choice of shelving. Has anyone else used bunnings garage shelving? They say they are rated to 180kg per shelf. Im picking each tank filled will be around the 100kg each. The metal is fairly light weight so being in good old Christchurch I imagine if we have any decent earthquakes the movement would just buckle and end in disaster.
Thoughts? Im contemplating building custom shelving instead using 4x2 but thought I would see if anyone uses this type of shelving.
