i had unreal coraline growth with my pc bulbs, dark purple and some of those weird fuzzy red patches. when i switched over to 10k 175's it almost stopped growing on the glass and it went white on the plastic but the rocks still look good. there are some coraline suppliments you can try, like "purple up" by salifert or a kent buffer with coraline accelerator.
