But water flows through them easily so I don't see a problem with them working with any media. So I'll say "Yes" they will work with Phosguard. **Q: Would this work as a filter guard for an internal filter in a freshwater aquarium?** A: If the internal filter can fit into the bag, I think it's a good idea! You can search on amazon:" Alegi fine bags" for different sizes! **Q: Are the zippers made of metal or plastic?** A: This is drawstring bags. It doesn't contain any metal. is completely safe for both fresh and saltwater aquariums. **Q: I have a cascade 1500 filter from penn and plax can I put 3 purigen bags in 3 of my trays amd what size bad should I use for a 55 gallon tank?** A: A basic purigen bag will treat up to 100 gallons for 6 months or so with proper regeneration. I use a 250ml bottle of purigen in one of the alegi media bags and have it in a wet/dry for a 90g tank. You won't need 3 for a 55. One will do fine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works With Purigen *by M***K on 8 August 2025* These are good quality bags with good stitching.
