thanks
When started was using a 60 - 40 mix of di and tap my mistake now I'm using straight di water, lighting is a coralife, aqualight w/ 2 - 65 watt actinic and 2 - 65 watt 50/50 in it.
I just started my first saltwater tank and my rock has turned yellow to orange and now its hairy and red anyone have any ideas what this is ? Should I worry and if so how do I get rid of this ?
