Spent some time with the tank and a hydraulic jack to properly shim the stand tonight. I did the best I could building the stand level but under the weight of all the glass it was clear that the floor was pretty screwy as far as level/hills.
To clear the hills in the cement I shimmed the stand in all 4 corners and under the other 4 vertical supports so none of the rest of the stand sits on these unevenly raised hills. I had a 4 foot level laying lengthwise in the tank and my 2 foot level laying across the width. Dead level along the 8 foot length and I am within a razorblade's thickness across the 3 foot distance.
Not really an exciting update I know. Once the bracing goes in tomorrow night I will frame the rest of the fishroom in so I can relocate all the insulation i have laying around down here into those walls! Fishroom wall and the wall around the stand will be insulated to keep the cold and the noise in the fishroom.
