I´m getting a new tank within the next month or so, and been looking at the above filters.
Gonna be running a 70-90 gallon tank
The 404 is half the price off the FX5, and the only diffrence i can see between the 2 filters is the "smart pump technolgy" and the bigger tank rating on on the FX5.
Is it woth getting the FX5 with my tank size, taking into account the big diffrence in the price aswell?
