## Questions & Answers

**Q: Does this come with any filters?**
A: One filter prefilled with carbon.

**Q: On the 10 gallon version, how far does the intake extend into the aquarium?**
A: Its adjustable, but my normal size and shape 10gal tank requires me to use this without the telescoping tube, and leaves the intake in a perfect place without it! The body itself goes 4in+ into the water so with that extra 6in adjustable tube (that gets almost 12in when extended) it didn't fit in my tank with the 4+in intake section connected

**Q: Can this be used for an Axolotl?**
A: Yes. I use that for my axolotl fir about 2 months. No problem. Very good.

**Q: Will this model of the Tetra is 45 handle a 55 gallon ok?**
A: The 45 model would not be enough for a 55 gallon tank on its own. Two of them would work, one at each end.
