[Delphinus]

Ok I hate to admit it but I think I'm at the end of my rope with these things, they're everywhere. They have literally infested every rock, every piece of equipment in my system, and my sump is full of them too.

If you have them, do you do anything to keep them under control?

Things I've tried, with varying degrees of success:

- manual removal. (Drawback: doesn't always work. Sometimes all I manage is shortening the shell, especially in an awkward spot)

- covering with epoxy. (Drawback: expensive. I have like about a trillion vermetids that need to be covered. Ugly too, but I suppose the epoxy could be removed at a later time.)

- injecting with kalk. (Drawback: only 50% effective so far, alignment is key and I just don't like the loose kalk floating around the tank).

Other ideas I haven't tried yet:
- boiling water
- lemon juice

Is there anything that eats them?
