apistasia outbreak....

[tebstan]

Careful with the lemon juice if the aiptasia is anywhere near a coral, it's easy to damage them. I've had good and bad luck with the lemon juice depending on what is nearby. The aiptasia x works well if you can get it right in the mouth. Aiptasia have a knack for growing where I can't reach them on the bottom of a base rock.

The group buy of berghia nudibranch was a little over a month ago... maybe they'll jump in with some feedback?
I would be interested in trying a few if I heard first hand experience of the effectiveness. How many does it really take to get the job done? They're pricey, and they may breed?

I had two in my 29, several years ago I only had 2 in my 158. The trick is to get at least one with eggs and or get three.

Another method is to inject kalk right at the base. Gone.

careful with copperband butterfly... they will also turn on your corals, esp. LPS

I use a paste of kalkwasser and cover them up with pumps off. I do get some return so I reapply the paste. Seems I can manage populations this way

Start over with new rock. It's cheaper In the long run...
