## Questions & Answers

**Q: Is it really refillable? I can open it and fill it up with another media? I want to fill this up with calcite.**
A: Yes, I have refilled the media, it is easily done.

**Q: Does it come full of media?**
A: I think so but its not the best media .I like the color changing media..

**Q: How do i open the canister to replace the di media?  it seems like i need some sort of filter wrench.  does anyone know where i can get that?**
A: Ramon, take a hand towel and twist off thread end. Righty  tighty  lefty loosey-! No wrench needed.

**Q: Can it be connected to garden hose?**
A: Hi Emy, No. the FD15 filter inlet/outlet can only fit a 1/4" RO tubing or a 3/8" tuning is you will use a 1/4" stem x 3/8" quick connect fitting.
