Some minor updates to keep you up to date
These are 2" pipes coming from the tank and into the fish room. I will use two of them for the overflow and the third is a backup/spare.
Today they started finishing the floors where the tank is and hopefully soon they will close up the flooring in the fish room.
MarkusII was asking what the signs on the tank said. I wrote "Please do not put anything up against the aquarium" and I also got it translated into polish since there are a few working there as well.
More soon
