I need to get a new filter, and I am planning to get the XP3 (Aquarium Pharmaceuticals RENA XP3 Canister Filter) since I have heard a lot of good things about it.
I know this filter is probably much much more than what I need (17 times the capacity), but I figure I will need a bigger than in the future anyway, and I don't want to get a small filter now and spend another to get a bigger filter later. Plus, price difference between a XP1 and XP3 is only $40.
Now, my question is, is there gonna be any problem with using an XP3 on a 10G aquarium? Will this create too much water flow in the tank? Or is it more like - when it comes to filter, bigger = better?
Also...with such big filter, can I get away with water change once every month?
