Saltwater to fresh?

[Mommachef]

I may have access to a free to me 90 gallon saltwater tank. I don't know much about it at this point, but I know it has rocks in it. (Forgive me I know negative amounts about saltwater, lol)
My question is..... Can I convert it to a freshwater tank? I'm assuming it is drilled and all that, but I don't know if that will really make a difference or not.

Yes you can. Chances are it will have calcium deposits that you will need to remove (vinegar water and elbow grease). If it does not have a filter you will need to use a wet dry filter or a canister filter can be plumbed to use the overflows.

That is awesome news, thank you!
