fx5 is sooooooooo over rated. Just saying...FX6 is already out in europe, might want to look into that. fx5 is already old news :P
Lets say this 90g is only for plants
900+ GPH thats 10gph per every gallon of water. I know water circulation is big for plants, but in a standard 90g with a footprint of 48" x 18" thats a lot of output current, that gph is up there for a full fish tank turn over
Lets say its for plants, and fish. At such a high turn over rate it dosnt make a great biological filter opposed to something almost half in GPH. Which is why the FX6 was drastically cut down in gph.
Just something to consider. I know there will be "i never had issues", "my fish are healthy" feedback from others, but it is what it is :P science is science, weigh out its options.
I'm not into the image, but into the hobby...
