How to get rid of tiny Aiptasia on frags

I use a syringe and inject them with lemon juice ,and then cover the hole with kalk paste.

if the sealing route is taken you can get super glue gel for 1$ per tube at dollarama. it works pretty good for a thick gel like frag glue if you cannot find/afford a big tube. it just really sucks popping open all the tubes if you have a lot of things to glue down.
