Curious what large tank owners are doing about their back glass- scraping, ignoring, mounting corals directly? With 8 feet of glass to maintain, this seems like a meaningful question. I currently have most of my back between the overflows fully exposed and accessible and am scraping the soft algae that's growing on it. Snails and blenny are helping but can't keep up. Not sure if I'm looking at doing this forever, particularly when soft algae become calcareous. What do you all do?
