## Questions & Answers

**Q: does this come with biobag and carbon filters or do u have to buy some ?**
A: Your initial purchase of the filter includes the Whisper Bio Bags ( 1 of them for the models 20, 30 and 45, 2 for the 70) and the Bio Scrubbers (again, 1 for the 20, 30, 45 models and 2 for the 70).  You should replace your cartridges on a monthly basis, but can rinse them in between changes.  The Bio Scrubbers should literally last forever, unless you lose them or damage them somehow. Wash these off in a bucket of tank water with a toothbrush.

**Q: Does it have a warranty**
A: Yes, it comes with a 3 year warranty on all manufacturer's defects. This does not include normal wear and tear or abuse, of course, but Tetra has a very liberal warranty policy.  If you need warranty help, call 1-800-526-0650.

**Q: Could you add a sponge filter to the intake so it becomes Fry friendly?**
A: Yes, you sure could!  You could use sponge media or filter floss.  Just be sure to clean or replace it whenever it becomes clogged.

**Q: Is this filter effective for turtles?**
A: In order to use this filter for a turtle aquarium, your water level must stay ABOVE the minimum water level line at all times, which means it needs to be within 3-4 inches of the top of the tank.  This is a problem with most turtle tanks unless you have a Turtle Topper. Otherwise, it will work well for a turtle tank.
