I've been tankless for a dozen years. Broke it down and sold it when I got a new house, new kids etc. Started looking around for another recently. Came across a doctors office looking to move their old display tank. Was a professionally maintained 200 gal reef that overheated and killed everything. They drained the tank and let it sit for 2 years. Rock, coral and sand still in it. Crusted salt on everything, sump has a 1/4 inch of salt, skimmer full of dried gunk etc. Tank is all custom built acrylic with hand made stand, built-in sump etc. They paid $8K+ for it new. I can pick it up for a few hundred bucks; maybe. I'm on the fence as it's more than twice the size I was looking for and unsure if I can get everything clean. Pump is probably trashed, and who knows what else. Thoughts?
