Review: Aquarium filter pads worked great - This filter worked well with my canister filter. Easy to install and clean. Fit well. I would recommend these filter pads.
Review: Fit perfectly. You could make your own, but WHY? - These pads are well cut and fit my SunSun perfectly. Sure, I could buy a roll of filter fabric and cut my own, because, you know, I like to work with scissors. Beats watching the game. For the price I would buy these every time versus making my own. Maybe your time isn't worth anything. Balance out your purchase with Replacement Coarse Filter Pad for Sunsun Super Grech Perfect HW-304, Set of 3 , as ideally you want more course than fine filters. I place a layer of two course filters at the very bottom, topped with a fine filter. Do not place a fine filter at the top (ie very top, just under the motor housing) of your stack! A filter in that location will certainly keep the particles from entering the aquarium, but a the expense of trapping the particles in the rest of your media (biolgical, carbon etc).

### ⭐⭐⭐⭐ Good, but wrong size.
*by N***K on August 25, 2017*

I accidentally ordered the wrong size (thought it was for the HW302 somehow), but with a little trimming they fit fine in my canister filter. Just be sure to double check what model your filter is before you order.
