Hello, My 18gal high tank has been running for about 9 months. Till now I have never had hair alge. I havn't made any changes to the tank recently. I got a new 96watt pc light about 3 weeks ago. Today I noticed the first signs of this hair alge. I run the light for 8 hours a day. Could this be the problem'??? Any ideas how to control this before it gets bad?? The solution MUST be reef safe. thanks.
