You may find it odd that we would review filter socks but efficient mechanical filtration is still one of the best and easiest ways to clear your water and export nutrients. Filter socks have been around for a long looooong time but not all socks are created equal, something that became clear when doing our weekly aquarium laundry of filter pads and filter socks. You see when you have a lot of tanks to clean, it no longer suffices to simply hose down the filter pad one at a time. For power users of filter socks and pads, only bleach and washing machines will do, but this treatment is rough on filter material and only the toughest can stand the test of time.
We’ve been using various filter socks for years now and almost all of them eventually split open and get turned into pads after about 12-15 washes. The generic filter sock is glued or molded together with a single stitch barely holding it together. As you can imagine, the basic construction of filter socks is no match for saltwater, bleach and then aggressively washed. Blue Life filter socks are built way more durably with double stitching at the seam, with another stitch winding around the seam of the filter sock. Furhtermore, the collar of the Blue Life filter sock is much thicker than the rest, with an additional stitch holding it all together.
Our first crop of Blue Life filter socks have gone through at least a dozen bleach and wash cycles and they appear no worse for wear, if anything they appear to be just breaking in. Although we were given this product to review, we would gladly buy Blue Life filter socks when they need replacement. If you are a power user of filter material and you use a lot of socks, the tough Blue Life filter socks are worth your consideration.
