My procedure for new corals is:
1. Remove the base of the coral...this helps fight nuisance algae and Montipora Eating Nudibranch eggs
2. Dip for 15 minutes in a treatment solution of Lugol's...most hitch-hikers will come off at this point...and I can see what I'm up against
3. Dip for 30 minutes in a treatment solution of Flatworm Exit...combats flatworms and adult nudibranchs
4. Superglue over all remaining areas of exposed dead skeleton on the coral...so only the living tissue isn't covered - also fights against algae
5. Re-attach coral to a new plug
6. Place in my 10g QT tank for at least a month.
7. Check weekly for nuisance algae or other pests
8. After a month with no signs of pests, the coral will be moved into the 55g...repeating steps 1-5.
9. The coral will sit in the 55g grow-out tank for a month. This is like a 2nd stage QT...but isn't a true QT tank.
10. After a month, steps 1-4 will be repeated again. This time, the corals will go into my 150g. There should be no problems with nuisance algae or pests.
I keep most treatments on hand just in case though.
