I would imagine a std FX5 would be too strong too strong a current, although if you can alter the outlet into a spray bar then this would work. My FX5 works a treat, but then its in a 180 gallon tank.
Eheim is my fave brand, 2217 spare parts are widely available, even though the clasic range was started 20+ years back, its probably the most reliable filter out there imo.
