  Overflow advice needed.

  Posted: September 28th, 2010, 2:32pm CDT by flamming angel

  Hello reefers :)
  
  Okay so i need advice on the overflow size. I am in the process on building a 600x600 cube and need to know the ffg:
  
  1. What size should the overflow on the base of the tank be. ie the overflow from DT -> sump
  
  2. What size hole should there be from sump -> DT.
  25mm, 38mm,40mm etc?
  
  Looking for the most common sizes and those that i can get fittings for.
  
  Thanks
