Review on 🐠 Aquarium Mesh Media Filter Bags with Drawstrings for High Flow Activated Carbon Filtration - Reusable Charcoal Bag for Fresh or Saltwater Fish Tanks by Beth Westra

Small Aquarium Mesh Filter Bags - High Flow 500 Micron - 3" x 8" with Drawstring. They work great, but now that I've discovered that I can get the same benefit with cut-length tights from the dollar store, I'm really sad that I spent so much on them. However, I bought them for biocarriers, not carbon, so I won't be emptying and refilling them regularly. If I were to use them for carbon I might see the point in doing so as packs of wet knotted tights would certainly be less convenient to open and reuse. May be.
