So I'm planning to setup a new small planted tank and am looking for the right filter. Being a big Eheim fan, I've locked my sights on the Ecco pro 200. It's rated at 600L/H, while my tank is 21Litres. Assuming that once filter material is in place, and an in-line heater is added the flow will be reduced by at least 50, it could be ok, couldn't it? Or will I be left with a raging whirlpool where no fish or plant will thrive?
