you can use prozy-pro but it may kill of your feather dusters if you have any or you can take them out and if you have one place them in a holding tank in the meantime if you don't have any then you you can just go ahead and use it. (p.s.) you are right about people miss spelling on this sight,but you are not dealing with rocket scientists.
Don't really keep cuc actually funny I keep 2 sand sifting conchs and when I put the poly clad back in it landed right by one of them they r really quick within a few seconds it was underneath the conch I figured oops that was stupid there goes my conch to my surprise the conch used its leg or whatever that thing is called that it pushes itself over rocks with to give the poly clad the boot it found a rock and disappeared !!!
Wish I had it on video really awesome !
Anyway I was wondering if the poly clad might eat other sp of flat worm
