to find a hitch hiking anemone that was not considered to be either a
pest or dangerous to fish, most always any desirable anemone are in our

always best to identify it before making any decisions as to its fate.
100ml distilled water, 1 teaspoon Red Devil lye (sodium hydroxide), and
2 teaspoons calcium hydroxide (kalkwasser). Mix well and use a PD-Tip
or dispensing syringe. Turn off water flow and let sit for one hour
before turning flow back on.
This mixture is also effective in killing just about anything you put
it on, including out of control xenia, polyps and even some hair algae
