I still run this one but it's not really a true algae turf scrubber. It's growing some cheato now but in all reality I am running the full zeo system so my reactors remove everything and actually I was going to remove the existing cheato as it is disappearing anyway. I do like this style of algae scrubber as it stays in the sump instead of above it. As for its effectiveness I can't really say as from about the last 3 months my system has been ulns.
