## Questions & Answers

**Q: Hey guys, what is the voltage? does it go from 110 v to 240v? i don't see it on amazon uk. if it doesn't work with 240v, what can i do? thanks.**
A: Thanks for your question. This filter is 110V and there's no way to adjust it to 240V for England. We wouldn't recommend running this filter with a power converter, so your best bet may be to stop by your favorite local aquarium store to purchase your filter.

**Q: I always buy the replacement carbon filters but where are the 2 black replacement foam sponge filters?**
A: When I buy these filters I throw away the black foam.I used the white filter fiber works so much better..and gets your water clean and clear faster..

**Q: I have a 56 gallon tall tank and need a filter that works well in this type. Will this model work well in the tall tank type?**
A: I think you will be happy with this filter. I am using one in my 200 gal fish tank I like it because 1. it is a good filter 2. It keeps the water oxygenated. ( lot's of bubbles )  :-) when I get my 75 gal tank ready I all ready have one for it.

**Q: What is the KWH for the 300 per day?**
A: idk but its probably not anything your going to notice
