Used Saltwater tank for Fresh water fish

[coalcut]

I'm thinking of purchasing a used 100 gallon tank that was previously a salt water reef tank. The tank will be empty and cleal when I purchase it. I'll be using it for fresh water with my own filters,etc. Is this a good idea? What should I look out for?

Thanks

My 70g is an ex saltwater tank and I've never had an issue. I just cleaned it with vinegar to remove salt deposits then rinsed it really well.

It won't cause a problem, if it is drilled you can cap it off.

That's going to be fine. Just look for the same stuff you would look for in any tank- inspect the seals carefully, look for chips or cracks, inspect the trim well (as this IS structural for many tanks), etc. If the tank is drilled for a sump, you can use that in FW too.

Sometimes you run across a tank that has old coralline algae on it, etc. This is pretty hard to remove with elbow grease alone, but it's easy if you get a paper towel, soak it in vinegar, and lay it on the affected area for 20 minutes or so. It'll soften right up and you can scrape it off.
