Is your water not insanely clear ? I had Pentair cartridges and even being the tinkerer that I am, the thought never crossed my mind to mess with the them. Even on a densely wooded property with oaks the filter had the pool near invisible most of the time. They filter down to 10 microns.........TEN millionths of an inch.....if you can see what it doesn't pick up, I need to come eat some of your carrots.
Unless you are just a tinkerer too. Then the answer is no. Move on to tinker elsewhere.
