ok guys/gals i've got an issue with my tank. i've currently got cheato in my display area and would like to remove it. i've tried the picking out manually but some of it is stuck onto the LR. My question is should i just pick up a Tang to eat it up or should i manually continue to remove it. I'm looking for some kind of prefilter for my return pump so that i dont have this issue any longer. any suggestions would be great. thanks.
