The sponge fits perfectly on my Fluval EDGE filter. It has kept the water clean and stopped my baby guppies from getting sucked in. Easy to install and maintain. I’ve used it for three months and it still works well.

Works great for catching fine debris like algae and fish waste. I noticed a cleaner water flow after installing it. A little bit of maintenance is needed every few weeks, but overall very effective.

My aquarium has small fish, and this sponge has been a lifesaver. No more fry disappearing into the filter. It’s simple to install and stays in place without shifting.
