I was worried as some people said their fish died but I changed mine out a few days ago and so far they are all fine. None of my fish have died or gotten sick. The water is very clear and my fish seem to be happy. I would highly recommend this product just don’t forget to rinse it very good before putting it into your tank. I feel that may be an issue for some. ... show more

    • Great filter cartridges
Size: 3- Count Style: Medium
As an avid tank hobbyist I need good filters and good cartridges. I am a fan of the hang off the back filters so these really do the job in helping keep my tanks nice and clean!! Easy to rinse off and put back until it needs replaced. 5/5!

    • Excellent filter
Size: 3-Count Style: Large
Easy to change and with a little effort you can clean them up and reuse them. After I clean them I ad carbon in them and I have a new aquarium filter.
