So I've got some used mp60qd's here and I'm wonder which spacers to use. I've got 3 spacers approx 1/4" thick and 1 that is rubber thin. Going on a tank with 3/4" acrylic. I believe there's supposed to be stickers on these but they must have been removed by previous owner. The pumps are from Jan 2021 if that makes a difference. Any help is much appreciated!
Just realized I spelled which like witch in the title lol.
