Last year, when my wife and I finished our basement reno. We discovered a foundation leak, luckily we did not have the carpet installers come in yet. The condo board had to hire a contractor to come over and rip out our brand new painted drywall

.
After they fixed it, the carpet was installed, and my new setup was off to the races. Fast forward a year, and my setup is running the way I want it. All my rocks have coraline, no nuisance algae, fish and corals are happy.
BOOM, my carpet was damp, baseboards soaked. I checked the area where the foundation leak was, and it was damp. Condo board sent a different contractor (he actually lives in my townhouse complex) and now they need to dig out the side of my house and rip apart my basement.
The area they need to fix is right where my setup is. I have been contemplating if I should try and empty the tank and slide it over. The stand is sitting on a big piece of plywood wrapped in plastic. However, even with the water out, the rock, tank, stand and equipment alone is HEAVY!
What would you guys do? Even if I move the tank over, I have to contend with dust from the drywall, and whatever else they need to do to fix this problem. They will need to inspect the underlay to see if there is any mold.
As of right now, I feel like ripping everything apart and selling it. Since we have been shopping for house #2, maybe its a good idea to sell off everything and start over.
Thoughts?
