OK. Two more ideas...
1) a list of the "accessories" you need. For example to do water changes I need a RODI, salt, buckets, container to mix salt water, heater, thermometer, power head or pump, power strip to plug the heater and pump, aquarium siphon, some way to get water from mixing container to buckets... The RODI, salt and mixing container are obvious; the thermometer not so much, until you're in the process and then you go "oh, yeah" and have to make that extra trip to the LFS. I've had a LOT of those trips and on-line ordering for stuff I just didn't think about.
2) Discussion on the state of wild reefs. I know some harvest programs will basically strip a reef down and others are done without cyanide and are careful not to deplete the resource. I'd love to know more about with locations are "good" and which aren't. Add to that a list of fish/inverts/corals that should be avoided becauses they are CITES listed as endangered. I teach ecology and so I'm being very careful about which fish/inverts/corals I get and where they come from but it isn't easy to find information on many species.
Thanks for this great thread of ideas!
