Filtration for my 4x2x2

[wynx]

I got 2 units of Ehiem 2028..and currently running one. Should I be running the 2nd unit.

Any thoughts, guys?

i found a single 2028 insufficient for my 422 and upgraded to a fluval fx5 for that tank. for my next 422, i've already bought (and intend to use) 2 2028s

More filtration is always better.
I used to run a 2228 and a 2236 for my 4x2x2.

I am running 2 2028 on my 4*2*1.5. Just nice I feel.
