How do I prepare an Acro to go in the tank?

[mark]

Burned twice with Red Bugs but I'm still adding acros after just acclimatizing them. Know I should QT but still have 3 Interceptor pills left.

Still sort of on topic, on of the reasons I don't QT corals is don't have a light for the tank. What would be the minimum light to quarantine SPS say in a 20g, and if was to get a light, how long to leave in a QT?
