I use both myself - about 2/3-3/4 LS and then the rest as CC for some "Texture" my 180 is LS on one side and about 2/3 way accost it starts turning in to CC just for diversity (but that only lasts until the next time it has to be moved too).
I've been into salts for less that a year though too...
Got the skimmer today and it looks perfect! Looks brand new as advertised and Reefy even took the time to put in some extra packing to insure the parts did not rattle around and get damaged........
Thanks again Reefy - Great deal, great packing and even shipped the same day - I wish all such...
