Just wondering if anyone can help with identifying what I have growing here. (Dark brown spots)
Tank has almost done a 2 week cycle.
All my parameters are doing good and this has just started to grow on a couple of rocks and the sand, it started 4 days ago as 3 or 4 spots then rapidly grew to other rocks and the sand.
Just wondering if I should be concerned or if anything I can do to prevent further spreading and possibly eliminate it all.
Thanks
