Hydor slim skimmer and tunze 9004

[Abbyreefer]

Looking to get back into the saltwater world and was curious if anyone has had any experience with either of the 2 skimmers. Planning on having a 30 gal cube reef tank (20x18x20 - medium load). Looking for something that will be as quiet and compact as possible (in the living room) also something that won;t have alot of micro bubbles go back into the tank.

Thanks in advance for any and all advice.
