Review on 🐟 AquaClear 70 Aquarium Filter Media Bags, 2-Pack, A1366 | Nylon Bags by Heidi Ramirez

I find the mesh size suitable for most applications and the price is quite reasonable. I haven't tried this with Purigen, but it seems fine as long as the resin beads don't start to fragment. The clasp is a simple cotton yarn setup but seems to work well. Hasn't rotted on my old bags in 2 years. I expect it to rot, but I have some nylon zip ties ready in case it happens. folded package. Then I fold it about 10mm to block the hole and wrap the thread around the folded material. You can tie a bow, slipknot or whatever. Wet cotton yarn is difficult to untie. So if you intend to access the content frequently, keep the node simple.
