rudy Posted March 26, 2006 Report Share Posted March 26, 2006 My 135 is about 9 months old now. The water is beggining to turn a bit yellow. I have pc lighting on it could the bulbs be getting old? I have probably 200 pounds of live rock, a coralife 220 skimmer, I change 10% a week. I can't figure it out! Is this normal? Quote Link to comment Share on other sites More sharing options...
BlkWolfe Posted March 28, 2006 Report Share Posted March 28, 2006 Yep its normal. More water changes or throw a carbon bag in somewhere. A fine coating of algea on the pane through which your viewing will also give the tank an overall yellow look, just take a razor to it if need be.
