Answer 2

Your principle consideration is the species of fish you are going to have in the tank. Too much power will batter smaller fish and the EX700 has a lot of spare capacity. The filter medium and running cost will also be quite a bit cheaper.

If you are planning a significant tank upgrade at any point then think big, but if this is a community set up, buy the filter that is made for the tank volume or you will find fish stuck to the intake filter.

Water quality wise it shouldn't make a difference, the output of the EX1200 might be greater, but the EX700 is well within its limits and fish only produce so much waste.
