Have you used Fauna Marin Algaex

I cannot seem to locate any current information on this product for GHA. I am thinking of using specifically on derbesia, which nothing else seems to kill.

Is the product still available? Seems like it disappeared about 2009 or 10

I just bought some from BRS

There are a number of threads about this product. It still is available online, at least.
