To Sump or Not To Sump?

[Oscar]

What are the pros and cons of a sump? I have still to make a decision on my first tank, but here is what I see so far:

Pros

• A place to hide equipment
• More stable environment due to larger volume of water

• Location to top up water, add salt etc
  
  

Cons:

• Extra noise of water cycling
• more locations for water leakage
  
  

Care to add to the lists?

Thanks
