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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ economicos y muy buenos *by J***S on 3 May 2024* silenciosos y funcionales ### ⭐⭐⭐⭐⭐ Excelente *by D***Z on 21 November 2018* El producto llegó a tiempo y cumple con lo esperado, buena calidad en materiales y es practico.
