Hello i have a profilter canister filter it stands roughly 31 32 inches tall and has a 15 -16 inch width im thinking its the pro70 but im not sure. I need to know what the dimensions are and which filter i may have so i can purchase a new prefilter cover for it. Can anyone help? Oh yea the profilter is hooked up to a 6 inch 452 vortex fan if this helps. ThaNKS
