I follow this for my newly acquired corals. I don't drip unless the water is far off from my tank. I only acclimate my lights using window screen three layers and remove a layer each week.
1. Remove the coral from the plug or rock the coral came attached to.
2. Add 3 gallons of tank water to your clearly marked and an carefully cleaned treatment vessel.
(Note: If you use a different quantity of water, be certain to adjust dosages accordingly)
3. Place pump and heater in treatment vessel (do not plug in yet).
4. Arrange your freshly purchased corals in the treatment vessel being careful to keep them clear of the heating element and the pump intake and output.
5. Start pump (not heater) and check that your corals are not being blown around, rearrange corals and pump if necessary.
6. Fire up the heater (double check it is set to proper tank temps)
7. Remove an Interceptor® tab from the bubble pack, and using your blade, CAREFULLY cut it into four approximately equal pieces (it is not necessary to be exact here, just get it as close as you can). Pack three of these four pieces in an airtight container for future use. Crush the remaining piece using the implement of your choice, take your time, and grind it fine.
8. Add the powder you just made to the treatment vessel. This stuff does not like to dissolve easily, so use a plastic mixing stick of some sort to ensure it mixes in, and does not just stay on the surface or stick to the sides of the bucket. This may take a few minutes.
9. Set your timer for five hours and forty five minutes.
10. When the time has elapsed, measure out the Betadine® at 3ml per liter of treatment water. Three gallons will take 34ml.
11. Set your timer for 15 minutes.
12. When the time has elapsed, remove your corals from treatment container, rinse with clean tank water, and place in tank
