## Questions & Answers

**Q: Does it fit the trigger sustem sumps filter sock holder?  The holes are oval**
A: I have a ruby 36 by trigger and the cups were a little loose. So my husband cut the rings off a couple of old filter socks and put the rings around the top of the filter cup and it fits nice and snug now.

**Q: And what is the best filter media to put inside?**
A: "Best" is 100% subjective based on the inhabitants of the tank and what you're doing. I use ChemiPure Elite or Blue (1 bag in as I've found two clogs it up).

**Q: can I put this in my sump w/filter floss inside ?**
A: Yes you can use filter floss

**Q: Will this replace 2.75 filter socks on waterbox aio???**
A: No - this is a 4" media cup designed to replace 4" filter socks. I have it on my 100.3 waterbox. I am not sure if RedSea makes a 2.75" media cup.
