Geiserailie 15 Pieces Aquarium Filter Media Bags 150 Micrometer Fine Filter Bags Mesh Reusable with Zipper for Activated Carbon Resins(5.5 x 7.9 Inch,Nylon)

These are awesome bags for your phosphate pellets and whatever else you want to use for filters that are great.

This is the second purchase of these bags. They are the perfect size for my fx4s and fx6 filters. Great for putting in Puritan and carbon. Can't say more about it very good products very happy with it

Works great as intended

Got these to use with purigen for my fish tank. And they work well, but they are slightly oversized and dont fit perfectly.

I like the zipper opening. The material and stitching is good. Great to divided my Purigen for my smaller filters.

Probably the best small-sized filter media bags I've used for my tank. I like they're a little stiff so they hold their shape in the water too. Highly recommend!

Keep my small jewelry in and organize 👍

Good for purgin!

En algunos reviews no les gustó el espacio libre del cierre para poder meter el material. A mí me pareció una ventaja puesto que lo usé para Purigen y Matrix. Buen espacio para filtros de nano acuarios de 8-10 galones

Fine mesh and works well

These bags are perfect for Purigen. Way cheaper than “The Bag” if you’re regenerating your Purigen I highly recommended these bags.

Ordered wrong size but amazing bags. Works for Seachem Purigen

Recomendado para el uso de purigen
