ugh, I have seen tanks with powerheads, I assure you I have as much direct flow as a powerhead with the AquaClear 300. I have it at the highest setting and for the first few hours it was on when I intalled it, the thing was blowing substrate everywhere. I think I am good in the current area. Now, I just need new substrate.
