Since my noob RoDi dip, I have used Bayers quite a bit. I have dipped SPS, LPS and nems with no problems. I did however almost dip a Clam and in reading, I would of made an expensive mistake.
My remedy is as followed
Float bag in sump for 10min to 20min
pour 1-2 cup of water and 3 caps of bayers in one container
remove coral from plug
11 min Timer
constant flow with turkey baster (only used for bayers dip)
Times up
drain most of bayers into sink (leave some to try and ID hitchhikers)
(4 small separate containers of tank water ready)
hold coral with tongs over old container, pour new tank water over coral so water falls into old container
Place coral in 1 of 4 tank water containers for 20 seconds.
repeat last two 3 more times or till last container is used.
Im not sure if dipping for 10 minutes would have a benefit over 10 seconds. Once I am done dipping, I want to rinse and dip to remove the bayers. I do use the last container to start hardening the glue on a new dry plug.
I'd say I have done this exact method on about 80 corals over the past 1.5 yrs. This thread is the last time I have lost a coral due to dipping. No unwanted pest with the exception of astrea stars from a chaeto purchase.
