Would you/Do you use an Algae Turf Scrubber?

Well it's definitely not NEW technology. I haven't seen any report of water discoloration on either FW or SW applications. I'm not sure why they aren't more predominant in hobbyist aquaria. It's a similar idea to running an autotrophic denitrator with sulfur or alcohol as an energy source (as in some public aquaria). The only issue I can foresee (which is preventable !) is when you do not clean your scrubber for weeks and weeks, and the bottom layers die and begin to decay causing an ammonia spike. There are scrubber designs though that prevent this problem... and realistically can you say it's a system flaw that negiligence causes potential problems?
