can flatworms become immune to FWE?

[GQ22]

after i thought i killed every flatworm in my tank, i just noticed a few of them. this time they look different. still brown but not as red as the the standard red flatworm. this one is brown and appeared to have s couple of white specs on it. Besides acro eating flatworms, will FWE kill every type of flatworm or is there a select few it wont kill.

BTW will flatworm eat other coral?

u probabaly can't get rid of all types of fw if u have intoduce new stuff in tank after used fwe. the important thing is if its the acro eating kind.

The flatworm that your describing is a pain to kill (but without a pic I can't be sure). FWE will kill it but at much higher doses than planaria, additionally you need to be relentless on the FWE.

GQ how many times did you dose FWE? I dose it at 2x direction, then followed that buy 1x an hour later. Did 40% WC. The following day I did dose 1x direction again and did 30% WC. One week later I did a 2x direction and 30% WC. It seems extreme but it worked. I haven't seen any flatworms since. I had the regular pod eating clear flatworms and the zoa eating flatworms.

Would the flatworm come from new additions of your collection because I recall you did the FWE awhile back already?

i didnt dose anywhere near what you guys did. for my 125 gallon i did one recommend dosage and then a day later i did another. after everything died and my tank was almost clean i did another regular dosage. i guess i'll have to try a 2x dosage. i dont think it should be hard this time as there was only like 10 of them i noticed.

by regular dosage, i mean half a bottle for a a full 120 gallon.

I hate flatworms!!!!!
