Live rocks turning brown

[clownman]

Hi there,

My rocks in my tank are turning brownish.

Is this good or bad?

Is there anything I should do?

Thanks.

ever considered whether there is enough current in your tank?

Did a search on the web.

This is what someone said:

"The black or brown on the rocks could be diablooms and a part of the cycle process. Putting a protein skimmer on the tank and doing a water change is just what the tank needs at this point. Make sure that you are not running the lights as that will add to your problems, lighting should be started with short periods and worked up from there."

Hope this helps for guys out there with my problem.
