Just wondering what would be good for the brown stuff on my rock. I got a powerhead to help blow it off, but it's not helping too much. I am able to blow it off but it just settles back on the rock. Any help would be great. Thanks
That sounds like diatomaceous algae. Is it a brown fuzzy looking growth? From my understanding it's not desirable but neither is it a huge problem, and it is also ubiquitous in new tanks. It's supposed to disappear about a week after it appears.
