Thanks for all the info. The base is drywall and below that is 1/2" OSB plywood, below that is a 2x4 frame. I have the same weight concerns. I have some pictures of the setup while it was being built and I think it will be OK or possibly might be a total disaster. I am going to fill it up very slow and see what happens.

It was built to hold a TV, but our TV didnt fit, so thats where the aquarium option came into the picture.

As far as the possibility of leaking. The owner of the LFS sold the tank to a customer a few years back and it was also built in. Then the LFS owner bought the tank aback (not sure why). It was setup when taken out of the customers home. I have his guarantee of no leaks, so I feel alright there. I think I will set it up outside just to check.

Thanks for the info on the skimmer, I'll give it a try and see what happens. Thanks also for the tip on the vinegar and water to clean it. I knew I would need to clean it all, just didnt know how. Thanks again.
