The foam pad works well for catching large debris. I changed it every 3 months and noticed a cleaner water flow. Easy to rinse and install. Good value for the aquarium filter system.

It’s effective at filtering out sand and sediment. I rinse it every few weeks and it lasts longer than expected. Works well with my 110-gallon tank.

Great replacement for my old filter pad. The porous foam catches debris efficiently and keeps the water clearer. No clogging issues after a few months of use.
