What eats this

[ongquang21]

I am using hot water to kill it and any coral such as GSP that is growing out of control.

I'm doing this because:
Cheap.
Safe.
Available any time.

Take a long 1/4 inch flexible air tube.
One end to the bottom of the hot water container above the tank
Other end to the hard tube that will point to the target.
Run the hot water over the target closely, slowly and many times.

Try at the target in the most open area first until you get used to it then try it in other ones.

You can see the area you was missing in a couple days later. But they are tiny now and you can't miss them on the second time.

At first I felt don't like it since it is an awful and low to the earth Tech. But I love it after i got my hands worked well in a tight area.
