Look up how to dip with Bayer. I've use lugols, revive and Bayer and the Bayer was far more effective and I haven't lost any coral frags with the Bayer yet. I have lost a couple frags with the revive though
I'm all sps. I acclimate my coral to my tank water for about 30 minutes. Then I use 8oz of water and add 10ml of Bayer. I mix it then I add the coral and leave the coral for 10 minutes. Once the coral is done in the Bayer I put it in a cup of only tank water for another 10 minutes, the. Use another container with tank water to swish the coral around to ensure no Bayer goes into my tank
Yea I've killed frags with revive before. I did 10 minutes in revive then 10 minutes in Bayer and it was too much for the acropora frags. So the combination of the two is too much for some coral
The makers of vibrant have a dip out that’s supposed to be very good
