I did an internet search, but I know it was mentioned on the marshreef.com site before too.
I've been pretty active there but after a recent plumbing episode
(H20+floor=PO'd wife and ruined carpet) I decided to give up my 75 gallon and began looking into nanos. This site has been the best resource for information.
A week ago I had no idea just how many options there were with nanos and now I'm waiting on my nanocustoms 6G nanocube to arrive.
I'm going to try and get out tomorrow or Wednesday and pick up the sand and Catalina Seawater. Then I'll just have to make up my mind on the LR. I'm now leaning toward the PA nano rock package. I've never been thrilled with any of the LR the local stores carry.
