Anyone see an issue with cleaning some rock in the tank with a new wire (steel) bristle brush for a short period of time?
One anecdotal report; I scrubbed some rocks in my tank with a plastic brush once to clean off some ugly algae.
Not sure what I stirred up, but doing so released something into the water that killed half of my fish and a few corals. Can you take the rock and scrub and rinse it?
Same dilemma here, my concern is the brush being free of oils
I would also test the brush on something before scrubbing in the tank to be sure wire bristles do not fall off.
