I'm curious here, by fully supported do you mean all the way around the frame? As in at all points of the bottom of the black frame there is a cinderblock in contact with it?
To me the last picture you posted where you showed where they were with red lines is better then it was to begin with, but it still isn't distributing the weight evenly. The points where the blocks are are holding all of that weight, and where there isn't a block has no support which to me would mean there is still a chance of failure in that.
I know this sounds really negative, but just as everyone else is, I'm just concerned that this will break on you and you'll be out the tank. If by fully supported you mean the blocks go all the way around then you should be good. Get some more pictures up when you can.
