You could have very well stated this already; but what model laser are you using? This is very interesting to say the least. I have a few pest aptasia that will not die even with the repeated dosing of aptasia x.The OD4 acrylic (the most expensive square foot of .140" thick plastic I've ever purchased) should arrive next week so I can start working on the endpoint shield. While I'm looking forward to testing the underwater host, I'm finding extremely easy to work through the glass.
Today I cleared a large patch of Xenia that had grown from the side glass (where I allow it and GSP to exist) onto adjacent rock work. It took a couple of sessions (due to the 60 second duty cycle of my laser) to eliminate it. I've found it sometimes takes a brief additional lasing in a few days should any survive. Even with that it's extremely effective taking less than 10 minutes in total.
The testing on Valonia was also effective. I found that a few seconds lasing the entire bubble resulted in 100% kill rates. The bubble fades and dissolves over the following few days.
Bryopsis - I only had a small amount on a frag plug to work with, but although it seems tougher, also withers and dies. It takes a bit more lasing time, but it seems to have been effective as after a couple of weeks it has yet to return.
Although much of the discussion has "focused" on eradicating Aiptasia - I'm finding it incredible to be able to easily control Xenia and GSP. As many that have introduced them into their tank have found, it's very easy for both to get out of control. Lasers provide a fast and effective way to manage both.
