鹿角台好散 is correct. you put the 鹿角台 on top of the rock or drift wood first, then use the fish string or anything to tie up onto the rock or wood. make sure you tie them up so most of them will stay. there will be some coming out that's no problem. so, you better risen by water before putting into the tank because there must be some 鹿角台 coming out.
you can search here for moss or 鹿角台, there are some picture step by step, so you can be sure how to work it out.
