...to my 240 gallon And WOW in 2 days I can see a big difference. I have to say they are pretty nice filters for the money. After a month and establishment I am removing my sump 40g filter completely it likes to leak water all over the place. Water is crystal clear right now and you can see down the entire 8 feet of the aquarium as if no water is in there.
