This is probably a dumb question, but I can't find the answer to it anywhere.
I got a few boxes of the 510 Platinum S series cartos and when I got one out tonight to punch one, I noticed the vertical bar running along the length of the carto. It looks like filler is exposed. I am assuming these don't need to be punched but just inserted into my tank. I read the specifics about them on the web site and am still confused as to whether or not they need to be punched?
Thanks for the help guys.
