If possible I would like to get your collective wisdom on something. I have Flatworms, and while usually i can deal with the sight of them, as of the last 2 days, I am done. they have exploded like Avril Lavigne on the pop scene...and like Avril Lavinge...i cannot stand them. So Im asking and begging...please MARS you are my only hope. I have a yellow wrasse, ive used SFE and for fear of my tank cannot use it again. What options do i have? any, or should i bite the bullet and nuke my tank with the SFE again?
