Getting rid of aptasia is easy.

First, welcome to Tonmo.
Getting rid of Aptasia is as easy as feeding them. I use Joe's Juice. You can read about it here,
Joe's Juice.
Disclaimer - It's no secret I'm an on-line retailer and I not only have used Joe's Juice for three years, I sell it. I've never used it around cephalopods but have accidentally spilled it onto corals without any affect. It's what I'd use in a heartbeat and recommend it to you. In three years I have not received one complaint and by the amount I sell, if there was a problem I'd know about it.
It comes with a plastic syringe applicator you suck some juice into and feed it to the Aptasia. In 20 min or less the anemone is history.
I don't know the rules here, (Does anyone read them???) so, if I get into trouble for this post, as I did on RC, so be it, I'm only trying to help with a problem.
