Is this marine or freshwater? For a marine tank I'd be aiming for about 10x capacity as the flow rate needs to be kept high. For a freshwater traditional enclosed filters capable for that size tank would run at about 1500lph but I'd go a little higher than this and suggest 3000lph. Don't forget to take into account the pump 'head'.
The compact 5000 is probably a good choice. Although you get 5000lph on the level by the time its pumped up a meter into the top tank the flow is less. Probably about 3000. You can always turn it down if its too powerful. Will you be ok with the noise? They're quiet for pumps of that power, but not silent.
