On larger systems I’ve always used them. On this nano I haven’t read a review of one that was worth it. From what I read the zeovit forums are very adamant that a skimmer is required but I’m hard pressed to see the downside of adding/feeding bacteria without a skimmer. I would think weekly WCs would sufficeSkimmer has multiple function their main job is to pull organic waste out from your water. Second they do make your water a little clear because they pull a lot of waste with color in the water and third they originated your water. So for me i use it mostly for the second and third reason.
