These are great! Make sure you replace them every 2 weeks especially if you got A lot of fish! I wouldn’t recommend only replacing your filter once a month with any filter I always try to keep replacing filters often.fie a healthier happy fish :). Enjoy guys.

This is a hard to find filter at this price. I just got the filters todays and they were shipped and packed perfectly. I just used one and its just as described. I am going to order more.

Unfortunately, this item was the wrong size for our fish tank and we were not able to use it. I have not been able to find the right one

As I said on the Large filter cartridges, I usually pay $5 for ONE! This time I paid $5 for 3! They only clog up after a month of use, when I change them.
