As long as you remove your mechanical filtration and shut off the skimmer for half a day it works well. I like the "scrape the stuff off with a knife" method myself. The little pieces settle into rock crevices and grow well from my experience. Tiny purple colonies start all over. Won't work nearly as well if it gets trapped in a sock or skimmed out though. Do it in the morning on a day you aren't feeding and dose a little iodine, strontium and magnesium if you need it.
