## Questions & Answers

**Q: Will this fit the cascade 300 hang on filter? here is the link https://www.amazon.com/gp/product/b0002dj82g/ref=crt_ewc_img_dp_2?ie=utf8&psc=1&smid=a2**
A: Thanks for your question. Yes, these filters are designed for the Cascade 300.

**Q: I bought a nine pack and only received three. Can anyone help?**
A: They come  in 3-packs. I've never seen a nine pack.

**Q: I have a 65 gallon aquarium for 2 sliders. How often should I change this filter?**
A: Hey Wendytime, 

Thanks for your question. As a general rule, we recommend you that you change the filter cartridges every 6-8 weeks. However, sliders generate more waste than fish and as a result, you should change the media more often. Your tank conditions will dictate how often they should be changed, but figure around every 3-4 weeks.

**Q: How do i know when the filters are spent? I had an algae bloom and changed mine out probably too quickly to try control it.**
A: I rinse mine and use them until they begin to fall apart.  But I also keep a new set in case of RIP or tear.  I love these filters.
