How to safely get rid of yellow zoanthids and green star polyps

[dedragon]

My friends tank is completely overtaken by gsp and yellow/brown zoas. I want to know the best way to deal with them as they are everywhere, I will get a pic later to show. Trying not to use kalk paste as there are too many and burning not really an option with zoas and paly toxin. Rockwork is also completely glued together so no way to take it out piece by piece. Any suggestions?

If done gently, GSP grows on a kind of purple mat, Ive removed mine from rock previously by prying up and tearing the mat off and/ or using a stainless steel blade. That has always worked for me as far as GSP goes. Im not sure for zoas, but if it were me, id wear gloves and cut them off at the base as if I were trying to frag them and just dispose of them.

If it was me, I would use the steel straw and siphon trick. This would keep all things submerged, no chance of fouling the tank and could be done a little at a time easily.

that is a good idea i will try that at first as it seems very safe. First i actually need to dremel a tremendous amount of monti cap and spongodes for him to even get into the tank
