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 ### ⭐⭐⭐⭐⭐ Very Fine Filter *by on Reviewed in the United States 15 October 2025* I'm surprised how fine the filter is for filtering. It worked great for what I needed it for; however, my little experiment ended up somewhat in a disappointment for me. I had rigged up a previous and out-of-date water pitcher that I had which takes those really cheap water filer, and I managed to fit the extra fine filter into the hole where the water filters normally goes for filtering, and I added activated carbon to it and overfilled it so there was bulge of activated carbon above the filter hole. The setup was perfect. However, the water went through the activated carbon really fast. It only managed to filtered out 10 TDS in the first pouring. I guess if I continuously refilter the water, it might bring the TDS level down somewhat. But the extra fine filter will definitely prefilter large debris in the water such as very fine sand. When I added the activated carbon to it and pour water to it for the first time, very fine powdered carbon came out of it which is normal on the first flush. Thereafter, the water was very clear. I guess if I used it for a fish tank, it would more than likely make that water crystal clear because of continuous filtering. The reason for the rig-up was I trying to make my ZeroWater filter last longer so it didn't have to work so hard in filtering. Those ZeroWater filters are extremely expensive yet it is the best water filter I ever used. ### ⭐⭐⭐⭐⭐ Uso para purigen *by on Reviewed in Mexico 8 December 2025* Cumple con el objetivo por el cual lo compre, para usarlo con purigen ### ⭐⭐⭐⭐⭐ Well made bags - 12x8 (larger size) *by on Reviewed in Canada 21 September 2024* Many reviews are for the smaller size so i thought I’d review the larger size. These are bigger than I needed, but the smaller size was too small. It’s OK, I will make it work. They don’t have a clasp for the drawstring, so you will need to wrap it around after pulling the drawstring or find another way to keep it closed. The sewing seems good, and the size of the mesh is good for what i need for my aquarium. These are flat bags, like an envelope, so they crinkle up a bit at the bottom when you wrap around the filter or pump (whatever you are using this for)- so its more like a sock, not like a freezer bag that you can stand up to fill. Thats fine, it’s just like the item description. I think these will hold up to multiple cleanings and wear and tear so I'm happy with the quality and price point. ## 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.sc/products/354455962-alegi-media-filter-bag-aquarium-extra-fine-reusable-180-micron](https://www.desertcart.sc/products/354455962-alegi-media-filter-bag-aquarium-extra-fine-reusable-180-micron) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-10*
