   well i may be getting a new tank and its not reef ready so will need drilled, and at that time i thought about drilling for a closed loop system too, was just wondering what the pros and cons are and if anyone runs them??

   I thought about it but decided against it.
   
   Pros are good flow
   
   Cons are
   Higher elec & heat transfer
   more places for leaks
   pipes will close over time with debris & growth

   By the time you purchase all the bulkheads/ and a decent pump you will probably have a lot more into it than just buying a few koralias. Powerheads would be much cheaper IMO.
   
   What size of tank are you drilling? Have you checked with the maker yet to make sure it's not tempered?
