Two 6105s or 6205s

[JFish180]

Hi Roger,

I have a 300 galon tank that is 8ft long x 30 inch wide x 24 inch tall. I currently have (2) 6055s and (2) 6045s, but I need to add more flow. Would (2) 6105s suffice, or would (2) 6205s be much better?

Your tank is long and not that wide or deep, so I would go with the 6105's which have a flow coverage of about 7ft by 2ft, vs the 6205 with just shy of 6ft by 3ft. 6205 is a wider flow.
