fish 511 add/buynothing right now.
Get a magnesium/calcium/alkanity test to begin with, seachem, elos or salifert.
Test before you get any corals, if it's really out of range, get the right supplement.
No need for trace/iodine dosing. You want a stable system, not a lab.
Soft corals won't need additive probably.
good advice there. it bears repeating
all this talk about whatever picked up when dosing iodine or whatever is anectdotal at best. that is absolutely no control for an experiment and many other things will affect the coral more than overdosing iodine, which will eventually get toxic BTW
1) alkalinity must be good period! you must have a good test kit and a means of adding carbonate. this is thee most important parameter in the tank. it is your whole buffering system.
2) you must have a decent pH test
3) calcium and magnesium are major traces and should also be tested and maintained.
4) calibrate your hydrometer/refractometer
5) have a decent thermometer
all the rest of that crap, forget about. just do waterchanges.
learn about the relation between alkalinity-pH-calcium-(magnesium) in the chemistry forums here.
edit: sorry sunfish, I missed your post before I started typing, so:
"yeah, what sunfish said too!"
