I have a 150g lookdown tub, dimensions at the top are about 5' long x 3' wide. I want to have 1 pump blow in 1 direction (the length of tub) for 15 minutes while the other pump is barely on. Then I will switch and have the other pump blow in the opposite direction while the previous pump is barely on. The rocks will only be stacked against a vertical wall in the middle of the tub so this will create somewhat of a gyre flow . Will 2 x 6100 pumps be enough for this? If not what do you suggest? There will be a SSB and maybe some softies/lps but mostly sps. Thanks!
