Review on 🌞 SunSun HW-304B Canister Filter: White and Coarse Filter Pads for Optimal Filtration by Erica Clay

These cases are well cut and fit my SunSun perfectly. Of course I could buy a roll of filter cloth and cut it myself as I love working with scissors. It's better to watch the game. For the price I would buy them every time instead of making them myself. Maybe your time isn't worth anything. Balance your purchase with the Sunsun Super Grech Perfect HW-304 Coarse Pad Replacement Pack of 3, as you ideally need more coarse filters than fine filters. At the very bottom I place a layer of two coarse filters, with a fine filter on top. Do not place a fine filter at the very top (i.e. at the very top, directly below the motor housing) of your pipe! A filter in this place will certainly prevent particles from entering the aquarium, but at the expense of trapping particles in the rest of the environment (biological, carbon, etc.).
