I can't believe how well these work, they last a while and wash really well for a few reuses. quality socks and I am getting more

The quality of these filters is very good, And a great value for the money. They perform really well in my aquarium filter, Having so many extra makes it so much easier just to switch them out when they get dirty, Then I just tossed them in the washing machine and they’re good as new. They’re very easy to clean, I suggest cleaning them a little bit to take out the heavy dirt before throwing them in the washing machine. Great filter if they fit your style of sump under your tank and they fit great.
