My opinion is that there are too many forums already. If a "nanoreef" was a lot different than a larger reef then it would make sense, but the 2 gal tank works under the same principles as a 10, 20, or 1000 gallon tank. BTW - so called nanoreefs have been kept for years. A search on the web finds quite a few.
Personally, I just check the recent posts anyway because I like being able to follow all the new posts. For instance the recent post by Suzy - it could have gone in an algae section or the filtration section but if Jake hadn't set up a recent posts list, I would not have seen it. Thanks Jake.
