Hi, I dont know if anyone has used this filter as it is new. I was looking at it and it looks like a good filter. I like it because it has the uv light built in and seems to be a reasonable price. What would your opinion be. Here is a link to the website. I am going to get the EFU 45 and use it with a Cascade 1000 for my 100 gallon saltwater tank.
