Review on 🐠 Aquatic Life Mixed Filtration Cartridge by Austin Wolf

I chose these because my last resin blocks sold out too quickly, a few hours of work and they were all yellow and ineffective. It was double vacuum packed and worked fine due to the poor quality of the previous company's resins, I had a problem with my large tank, several days of water changes, my PPM counter still reads 0.00 and all the resins are still like new ( from what I see). Another consideration alongside another brand was the refillable cartridge and just getting new beads seemed like less waste and this company only has beads in packages. I've noticed that the competing cartridge is also refillable, I've also seen beads going through the materials on the bottom and those pads on the bottom cap may also need to be replaced. So I can simply buy a new cartridge when changing beads, freshness is more important than ecology.
