How good is my filtration?

What do you think? It is a 20 gallon tank with a penguin 170 and an aquaclear mini. Im getting shell dwellers.

I don't think there are enough choices because just perfect and awesome are like the same thing. The middle choice should be something like good, not really favoring either way.

the middle one is like the exact amount that would be needed. Awesome is overfiltered.
