Okay. I have a 180 gallon with about 300 lbs of live rock. I just noticed little gold eggs on one of the arcos. I threw it out in hopes it was only on that one. Wrong! I just noticed today that my milli's PE hasnt been the same. I basted it and what looked to come off was AEFW. SO my question being I have around 60 colonies all encrusted to the live rock all over the tank, Has anyone had any other experiance getting rid of them other than dipping everything? Adding a fish? Treating the tank with something? Anything would be wonderful! Thanks!
