would you even need the hob if you went with the fx5 i mean isnt it rated for 400g?
The "up to XX gal tank" rating on filters is useless... the AC 110 is rated for up to 110 gal tanks...
Either filtration option originally mentioned would be able to do a sufficient job if set up logically...
Decor has a big impact on filtration... If your decorations make dead spots, you have to overcome those dead spots with current...
The fish you stock in the tank will have a big impact on filtration needs. Tetras make little poop that slight currents can easily wisk away into a filter... but adult PBass make huge poop that weighs more and takes more to move into an intake...
The amount of maintenance you wish to do on the tank also has a big impact. If you would be happy to commit to frequent vacuumings, then strong currents aren't at all necessary. But if you want to make the system require little personal work to keep it looking fresh, stronger currents are necessary.
The flow rates of the AC + FX5 will be a lot stronger than the 2217's... so in most cases I think they will be a better choice...
No filter has a better reputation than Eheims, so if you are stockign small fish you may consider them though...
Either way you may want to add some powerheads... but you can set things up without them and see what you think. Then add them if and when you need them...
