Hi guys. At the moment I have a 150l planted tank. Iāve got a box filter (what come with the tank) and an external filter. They are both running at the same time but Iām almost ready to take the box filter out and just let the external do itās thing. My question is how much surface agitation should I have for my planted tank? The box filter sits High at the moment and provides good agitation however when I turn it off the external doesnāt seem to be aggitating it as much.
