Yes, mine is mostly in wall. about 12inches will show on one side when it is all done. I am going with 77inches cause my girlfriend insists that it is worth the extra money to make it match the spot we have for it. 4 inches for $500 seems crazy though, lets see if I can use her argument when it comes time for the skimmer.
I decided to go with the tunze streams for flow, not doing the Cl's. I will add two tunze wave boxes down the road if I need to.
I am leaning towards an ASM skimmer, but size under tank is a bit of a proplem. The deltecs are sooooo expensive. I bet you will love it though.
I decided to go with James when I read the thread on the 340 front hex. That tread was one of the reasons I am going with the tunzes too.
I hope to have my tank in November so you will be leading the way
