## Questions & Answers

**Q: what are the dimensions?  are they the red sea 4.5 inch diameter ones that fit their reefer sumps?**
A: Yes, they are designed for the Reefer.  I will say that I no longer use them.  For some reason, mine would get a slick film on the outside of the sock, so when you would lift it out to change it, all this slime-like stuff would come off in the sump.  I bought a plastic filter media cup that was designed to replace the socks altogether.  It is on Amazon also....
