Recycling my old tank

[Jigsaw1982]

Soon I will be upgrading from a 26 gallon to a 110 gallon tank. I am thinking about recycling my old 26 gallon tank and using it as 1 of 2 things. Either a Frag Tank or a quarantine tank. Can I get some input on the pros and cons of each and some opinions on which would be better to go with and why. Also if anyone has any good designs I would appreciate it.

I would say use it as a QT tank, as most don't like to put new fish into the DT not knowing if they'll give the other fish a disease. Once you have all the fish you want in the tank and are not likely to add more, then switch to the frag tank. Providing you haven't used copper in the tank.
