can I target-spot shoot hydrogren peroxide inside DT for GHA?

[RioReefr]

In the past, I have had success dipping some coral frags with some GHA briefly into the solution of tank water and hydrogen peroxide. Typically it would be 1/2 tank water and 1/2 3% hydrogen peroxide in a coffee-cup. The GHA on the fraq quickly turns white and fizzles away. I let in there for 1-2 minutes, put the frag into 100% tank water to wash it off then insert the frag back into the tank.

Here's the thing: I have this green-star polyp that has encrusted itself onto the biggest rock in the tank which in no way do I want to remove that rock. So.....

Could I take 10mL syringe filled with hydrogen peroxide with a large 18-gauge needle and target shoot the green-star polyp (which has some GHA on it) a few times inside the tank?
In the grande scheme of things, 10mL seems like a trivial volume compared to the overall DT water volume. BUT, I am always so paranoid doing stuff like this.

Any thoughts?

Dosing 1 ml per 10 gallons of hydrogen peroxide is one of the ways people suggest beating dinoflagellates.

It won't harm your tank. The local store I'm near suggested using a sponge, soaking the sponge in hydrogen peroxide, then pushing it up lightly against the GHA. You aren't trying to squeeze the peroxide out onto it, just enough that it soaks in.

Maybe try turning down the flow to make sure it stays in the area if you are using a syringe, but it should work.

I love that idea of expelling the H202 using the sponge against the green-star polyp ! (This forum is so awesome sometimes)
At night all the polyps subside and basically it just looks like someone put chewing-gum on my rock. I am going to try this tonight....thanks so much!

No problem! Hopefully it works for you.
