I have used these for long enough to trust their durability. Review: Very Fine Filter - 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 I had rigged up a previous and out-of-date water pitcher that I had which takes those really cheap water filer, and I managed to fit the extra fine filter into the hole where the water filters normally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. ## Features - Size: 7.5" * 3.6",180 microns fine mesh drawstring filter bags, Suitable for 100ml fine filter media. - Specially designed for extra-fine filter media and activated carbon. - Seal the bag securely.

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 Seachem Phosguard *by C***9 on September 8, 2026* I bought these specifically for use with fine-grained filter media such as Phosguard, Purigen, and Hypersorb.
