My first question would be what are you using as a filter and what is it rated at? I try to go for at least 10x circulation around the tank, so try to shoot for 420GPH. If your filter is rated for 300GPH, I would say it's actually only around 225GPH after filter media is taken into account, I would shoot for a powerhead around 200GPH.
