I have a standard 55 gallon and today I noticed that there was all kinds of detritus on the gravel so I stirred it up with a turkey baster. I looked at my flow and it really doesn't seem like enough to me. My filter is the SunSun 302 so it flows about 150 gph and that was all I was using. I added an old SEIO 620 I had lying around and closed the inlet a little. Now all the crap in my tank is stirring up and my plants are waving around. The tetras in the tank don't seem to mind at all but in none of the videos of other planted tanks do see this much flow. I come from the reefing world so when I think flow I expect something to be bent in half before we have enough. What do you guys shoot for? I figure I've got about 10 times turnover in the tank and 2 times through the filter.
