How many filters do you use???

Subject: How many filters do you use???

Just read this on a website...

“If possible, give preference to two smaller, independent filters than a single larger one. It makes things easier for you and more secure for your tank - if one of the filters clogs or stops working you don't lose all of your filtering capacity.”

Can see the logic obviously. What do people actually do? One or two filters... more??

Currently purchasing items for my new tank. I was going to be buying the Fluval U4 but now wondering whether to get two of the U2 or a U3 and a U1????
