How much water flow is ideal for a planted tank? I know these are broad terms, but my filter (I have a top fin-60 filter, for what it's worth) has a max setting and a minimum. I can adjust anywhere in the middle. On the max, the flow is strong enough that it makes a couple plants under it sway, this is in a 40g. On the minimum, a small tetra can swim by it and not even have much resistance. I don't care either way.. but is one beneficial for the water/circulation/etc?
