Well, I was sort of hoping to update this thread with some of the good progress that has happened (remember it's not really a tank build, it's a whole basement build, and all the good fun that comes with that).
However, ..
I'm just about at my limit with the unpleasant surprises. Tonight I found my concrete floor under the tank is disintegrating away (literally turning into powder).
Something of a showstopper.
Is there anyone on the board in Calgary who is a concrete contractor or something of this nature and can please contact me? I need to discuss causes and cures and how I'm going to fix this.
I'd post pictures but I'm seriously ticked off at the moment and just want to walk away from it for a bit.
