Tank placement and levelness on the stand
I just built a stand for my 50 gallon tank and was setting it up but had some support questions. First of all, I got the stand so it is totally level, and the plywood is also flat on the top. Its basically a 2x4 frame top with a sheet of plywood on it. I ran a straight edge along the top to look for any warping and did not see any. When I put the tank on the stand, it sits on it level and without any wobble. However, when I look under the front and back of it, there is a slight gap where near the middle of the front and rear spans is not making contact with the stand. We're talking about the width of a business card. I filled it with water to see what would happen and it didnt really change much, that small gap was still there. Just to be sure it was not the stand, I placed the tank on a granite surface and found the same slight gaps.
I am confused as to whether or not this matters because I have read in some places where every part of that frame must contact the stand, and I have read in other places that just the 4 corners or the two sides need to be. I am certain my stand is much sturdier than some of the commercial stands, and I do have it completely level with no wobble. I just want to know if that front and rear span is going to hurt anything if it is not touching, or if i should slide a thin shim under the middle.
