Fragging
SPS usually entails breaking a small piece off the colony and attaching it to a rock or reef plug with gel type super glue.
Fragging soft corals...most of them...entails cutting a piece off the mother colony with VERY sharp scissors or a razor blade. Super glue usually won't hold these as they produce too much mucus and will undo the glue job. I usually use bridal veil and super glue to strap the cutting to a rock or plug. Another method is to put the cutting on some coarse substrate and let it attach on its own. You can then glue the substrate to a rock or plug.
LPS is different in many cases...pretty much depends on which coral you're working with. You can break a piece off of a torch coral and relocate it in the tank...it will grow. If you break a bubble coral, you will likely damage the polyps and open the door for infection.
My 10g reef had a 3" sandbed, about 20lbs of
LR, a Lee
CC skimmer, and two MJ400
PH's. I started with NO lighting and graduated to two 36w 50/50
PC's. Like Hoops, I did about a gallon a week water changes...sometimes 2
gal. I had an assortment of snails, hermits, and one brittle star. Also had one fire shrimp and one ocellaris clown. Tank was very stable and did great until the chihuahua knocked the heater plug out and the temp dropped to about 68* one day. That was the end of the clown.
In retrospect, I probably didn't need the 3" sandbed...and possibly didn't need the skimmer. It did pull a good bit of gunk out, but took up a lot of room and was pretty ugly. Water changes would probably have taken care of things just fine.
JMHO.
