I do have a question about my Colt coral- it dislodged from the rocks and wound up in the bottom of
the powerhead! I do not recommend powerheads in the tank just for this reason, among others.

Part of the ends were torn.Is there anything that I can do or it is a wait and see game? I would
recommend a wait and see. Make sure the base of the coral is either attached with a *light* (not too tight)
rubber band or firmly wedged in between the rocks where it can begin to feel secure and attempt to re attach
to some base rock. The colt is a very hardy beautiful, species and I would venture a guess that it will be ok.

Also, I have a green star polyp that is about two weeks old. It has not come out since my last water
change, about one week ago. Is there a problem here?

when you did the WC

did you match the salinity?
pH? temp?
Did you use a quality salt? like IO or Coralife?
Did you change anything else?
if you answered yes to all but the last question your polyps should be fine.
How long since the last WC?
How much changed? It sounds like you probably changed at least 30% or more and that's why they are
reacting as they are.

Star polyps are hardy but are giving you some experience as to the sensitivity of the corals. I recommend to
change 12% every 2 weeks that's a very good maintenance schedule. If you don't follow that... at least try and
be consistent with smaller amounts. Water changes IMO are the best maintenance you can do and helps
eliminate guess work as to adding trace elements etc. I think your corals will be fine just possibly rethink
your maintenance plan.

I understand the goals of the water treatment equipment, and the function of the live rock filter. I'm
planning for a high intensity lighting system so I can keep a wide variety of corals, hence water quality
is paramount.

Ok well...IMO a "wide variety of corals" will have a equally wide variety of demands. As you know I am not
a proponent of extreme wattage, which has been one of the reasons for doing my survey Id suggest to have a
look at that. Anyway, again IMO I would recommend easier to keep corals and usually...the higher the light
requirements the more difficult to keep. For example a HL SPS tank will consume a heck of allot of calcium,
so a calcium reactor may be in order and depending on your physical location the heat from the lamps and
pumps usually transfer to the water so If your in this league.. a chiller may also be called for. Keep in mind a
wide variety can really be *a wide variety* but the long term costs of operation is damn costly Believe me!!
