View Full Version : Help!! How to Scrub Live Rocks??

02/02/2008, 09:02 AM
Hello all,

I HAD a Cyano problem, I used Chemi-Clean, and it worked!! All the Cyano is DEAD, but it is still attached on the rocks. My plan is to get a couple of Rubbermaid tubs, get the rocks out, and scrub it off of the rocks, and replace rock back into the tank. I'm leaving all the live stocks in the tank, only taking out the rocks!!

Here is my question,

The water in the tub to use to scrub the rocks, can it be just RO/DI water with NO salt?? Or do I have to make another solution that is the same specific gravity or salt level as the tank itself??

Thanks All!!!

You should be using tank water, just do a water change and use that water. Fresh water will kill your live rock, think of it like it's an animal.

I agree with o.c.d. use water out of your tank and just do a small water change

IME you'll need three containers of saltwater. One where you do the dirty brushing and rinsing, a clean rinse, and a holding tub for excess rock while you reaquascape.

Any live rock put for any time in fresh water either RO/DI or other will be dead rock with another cycle.

I agree...use the water from a WC

I agree with amu when I did mine the water gets very dirty fast!!!!!!!! and if you only use one container you will be scrubing dirt with dirt

I did it just as amu says I did a water change 30 gal and used half that water for scrubing the other half for rinsing and fresh salt water to hold befor putting back in tank. Oh yea its going to smell the shore on a bad day.

You can use a toothbrush or any type of kitchen like scrubbing utensil. Make sure you purchase it new and that there's no extra additives. Then wash it off really well with tap water before use. Toothbrushes are good for crevices but since you're probably going to be using a lot of rock get one of those scrubbing wand brush things.
