Generally, clarifiers are not necessary, if you stay on top of your chlorine and CYA levels. That being said, there are very, very rare situations when a clarifier is helpful-- when you have particles that are just too small to filter out. Last year I replaced my filter and filled it with zeosand--and then turned it on to "filter" without rinsing first. That created a mud pit that would not clear after 2+ weeks of filtering. In that case, a clarifier cleared it in 24 hours. But that's a very rare necessity, and a mistake Ill never make again!! :0)
