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 ### ⭐⭐⭐⭐⭐ Keeps biofilm from clogging drip emitters 🙌🏼 *by M***. on 4 February 2024* ### ⭐⭐⭐⭐⭐ Works With Purigen *by M***K on 8 August 2025* ### ⭐⭐⭐⭐⭐ Uso para purigen *by G***A on 8 December 2025* Cumple con el objetivo por el cual lo compre, para usarlo con purigen ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/354455962-alegi-media-filter-bag-aquarium-extra-fine-reusable-180-micron](https://www.desertcart.us/products/354455962-alegi-media-filter-bag-aquarium-extra-fine-reusable-180-micron) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-10*
