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. ## Frequently Bought Together - ALEGI Media Filter Bag Aquarium Extra Fine,Reusable 180 Micron Drawstring Mesh Filter Bags for Very Fine Resins Filter (7.5"*3.6" (3 Pack)) - Seachem Indoor Purigen Organic Filtration Resin - Fresh and Saltwater 100 ml - Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 500 ml --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/181547272-media-filter-bag-aquarium-extra-fine-reusable-180-micron-drawstring](https://www.desertcart.ec/products/181547272-media-filter-bag-aquarium-extra-fine-reusable-180-micron-drawstring) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-17*
