How to eliminate aefw in bigger tank with many colonies

[gcp123]

I have a 5x2.5x2 tank with about 100 sps colonies. The tank has been running for about 2 years. I have recently noticed that a few colonies of sps not doing well. So I took them out to dip in bayer and was shocked to notice that there is a lot of aefw inside. Then I took a few other colony out to dip and check and found to have no aefw. So I believe only a few of my colonies are infested right now.

Luckily since day 1, I have been using acrylic tube and rod to mount my sps to facilitate shifting of corals. So there is no encrustations of sps on my liverock. I can easily take the 100 colonies out to bayer dip for 4 weeks.

My question is instead of setting up a separate tank to house the corals, can I dip the 100 colonies and put them back into the main tank and do this every week for 4 weeks?

What about the liverock? Since there is no encrustations can I keep them inside or I have to remove all the rocks?

Thanks.

In theory your method should work. You'd have to be very diligent.

I think it could work, but that 4 week timeline will probably end up being 8-12 weeks since you might have some strays on your rocks too.

I tried that procedure for 4 weeks but they did come back and I was using RPS All Out for the dip. I had frags on egg crate so I changed the eggcrate and stand offs at the same time as I dipped all the frags.
