Aipstasia on maxi shell - should i kalk paste them or leave them go

[E-A-G-L-E-S]

One of my maxi's has aipstasia on it, 4 of them. They are still small.........should i paste them or let go?

*one is rooted just 'inside' the top edge of the shell, so i'd be worried about getting any kalk drippage on mantle?

i used a tooth brush to get them off.

yeah i'd say the easiest method would be to just scrape them off
