Review on Enhance Filtration Efficiency with Marineland Bonded Filter Sleeve for Magnum 350 Canister Filter by Patty Martin

When we bought our Magnum filter system (used) every month the previous owner took the filter material and cut it to fit the filter block. At first I thought it was a financially sound decision. However, after our shipments ended, I found that the price of these blocks is only slightly higher at Revain. However, they fit the units perfectly - covering all areas exactly as they should be, and they're fairly easy to remove and replace without too much hassle (whereas manual trimming and installation was a hassle for both cleaning and installation) . so that they match the filter).
