Great, I was really concerned a week or so ago when I noticed the coraline on the back wall of my tank started to turn white....then today I notice that it is growing back.....not sure what it was but it is an up and down type thing. It is a good thing but I curse it like crazy when I am trying to clean powerheads and skimmers of the nice hard purple stuff.......hehehe...
