I ordered this:
www.poolsupplyworld.com
Now if you open that link and look at the pictures, there is a picture of a tiny filter attached to a port on top of the filter cartridge by a tube. Anyone know what that is for? My current cartridge doesn't have that little filter attached. I am wondering if the cartridge that is arriving today, and if I will need it? What is it for and what does it do?
