Lately i have notice foam in my sump were the water drains into the sump. The tank has been up and running for about 10 months now and this has never happened before. Is this something i should be concerned about? Is there anyway to keep the foam from collecting? Every thing in the tank seems to be fine but i do feel like there has been a lot of algae grow as of late. If anyone was has some advice or idea i would really appreciate it thank you
