When should I replace my filter bags?

This depends on the size of your aquarium and the amount of livestock you have present. You can be the best judge of your own aquarium. Being made from felt material they are easily reusable after washing in a standard home clothes washing machine. We recommend replacing them after 20-30 wash cycles

    7/5/2019: I received my 4″ socks today fast free shipping product is as described. one suggestion I would make is to display the socks with a black background on your site so they can standout. other then that look & feel heavy duty and will do a great job trapping crud

    Thank you.
