Enough Filtration?
I am planning a planted 20g tank and am wondering if a pengiun 170 filter would be enough for it. I was thinking of an undergravel filter as well, but I don't want to take away any of the CO2 with the air bubbles from the plants. I could get a couple powerheads but they are kinda expensive. So would the 170gph power filter be enough. only about 10 small tetras in the tank.
Thanks E
