I’m looking to see if there are better things out there to clean my cartridge. I was looking at something called the Aqua Comb attachment for cleaning cartridges. It sells on Amazon. Right now I just use hose without any attachments. My question is are these types of attachments that have these “fingers” - are these actually supposed to be placed in between the pleats? Thinking that could separate the pleats and make cartridge less effective?
