Purple Cloves taking over

[StReNuOuS BiOmArKeR]

do what i did is get your nitrate and phosphate down to zero and watch those puppies melt away......but other corals will also suffer. you might have to give to take

I made the same mistake a couple years ago. My whole tank is covered with them. Although they don't seem to bother anything but zoos. Most people like the look of them when they come over. I definitely will be buying all new rock with the next tank:-)
