Something crossed my mind while driving home, kind of left me dumbfounded...and I wasn't sure if I am the first one to have considered this, or if I just have a misunderstanding of whats happening.
Now if you have a sump with a return pump going at 600gph, would you add the water draining at 600gph to it to give you a total of 1200gph of movement?
Then I thought well, if you compare a whole sump setup to a koralia, which I wasnt sure where I was going with that thought, but it led to another thought. If a koralia is rated at 600gph, does that mean its only putting out 300gph, but also taking in 300gph for a total of 600? Either way, water is moving from both sides of the device, if you were to place your koralia towards the surface of the water face down, you should still be able to see ripples at the surface where water is getting sucked in....so I would think.
Or is the 600gph koralia actually inputing and outputting 600gph each, for a total of 1200gph of water movement.
Maybe I am over complicating the idea of powerheads and turnover rates, but regardless, both the input and output of a sump is going to break surface tension of the water in your direct tank, allowing for more O2 exchange, and since they should flow at approximately the same rate, I cant imagine either the input or output having any more or less of the effect on the exchange as each other, so you would have twice as much flow as what your return pump is rated for. But the concept seems to change when it comes to powerheads.
Thoughts, opinions?
Personally I think I am just overcomplicating the subject, but am curious as to what anyone else thinks.
