So I was dosing about 5 ML FWS daily for about 70 days. I noticed a TON of eggs after that time period on one of my smooth skinned stags. After that I'd had enough. I finally tore down my tank to the point where I ditched 60% of the rock, de-encrusted all acros and put them on tiles, then started dipping with CoralRx. I'm dipping all acros every 7 days. I just finished a dip last night, less worms came off then last dip, and noticed way fewer bite marks. Did FWS help? Probably, but I didn't want to see the rest of my acros getting eaten while waiting another 4 months.
What I'm doing now is 2 ML FWS daily, (for ~60 Volume gallon total) and weekly CoralRx dip. I think that should speed up the process to get rid of these ravenous pests. We'll see ;-)
