I'm a little concerned about the output on my Aquaclear 70 filter. I have it turned down all the way, but the current that it creates is pretty high and I've noticed that it kind of pushes the fish down when they swim by it. Today one of my new rainbows kept swimming against the current as if he was determined to get through it but of course he couldn't. Is this something I should be worried about? The fish seem fine otherwise. I have a 55g tank so I know the filter is not overkill. Thanks.
