I'm finding tons of information online about how to propogate corals but I can't find a good resource about how to set up a frag tank. I'm assuming that a 10 gallon tank would work, and it looks like most people make tiers out of eggcrate, but does a frag tank require filtration? What kind of lighting? How often do you need to do PWCs? I'm guessing it would have the same requirements as my main tank for flow and temperature.
If you have the answers or can point me to a good resource I would really appreciate it. Thanks!
EDIT: one more question - how do you feed a frag tank? and do most people have their frag tank tied into the main system or completely separate? okay, that was two questions.
