I need to clean off a pump that is covered in dead coraline. I am also in the process of cleaning my empty tank, so i would like to get rid of the coraline. any help is good...
I usually only have to soak a coraline encrusted powerhead about an hour in a 50/50 vinegar solution. Vinegar, I tell you, is a great thing. So useful for so many things.
