## Questions & Answers

**Q: I have an outside fish pond with a bio filter canister system. Should I run the uv before the canister filter or after the filter**
A: After. Using the post-filter water will keep the UV sterilizer clean longer. Organic build up on the bulb will require more frequent changes.

**Q: Can this model be installed vertically?**
A: Yes it can.

**Q: How can I contact the company for warranty service?**
A: Should be with your paperwork that came with it.

**Q: Where can I get 90 degree elbows for this?**
A: According what type of hose you have connected to the uv light , most hardware stores will have something you can make work if you take a piece of hose with you when you go.
