Double dipping new frags?

[ChrisfromBrick]

just got a couple frags and there was some nasty stuff on the plug and i don’t have a QT tank. I dipped coral RX followed by a h2o2 bath for a few minutes. The zoas got a very concentrated peroxide dip and the chalice less concentrated.

Would it be a good to dip again tomorrow with a water change or am I overthinking this? Will Inbe doing more harm than good? If anything survived that dip, it could cause mega problems.

Once a frag goes into a system the bugs it carries are free to invade the environment. The exception is for macro algae, if they sprout later removing them after the algae is visible may prevent a successful invasion.
