In response to more flow via the tunze pumps. I looked into them but since I was running the reefkeeper they would not support the constant off and on.
So I choose to go with the maxijet which are proven over and over to be a great pumps.
You have to understand the tunzes and seios are designed to create turbulance not steady stream therefore enhancing the spectrum for the likes of clams and sps.
In order to achieve the seio or tunze affect with maxijet pumps, you require collision of streams and that is what the reefkeeper does; it allows these jets to collide and create turbulance if the given angles are worked out.
I personally do not like the look that Tunzes and Seios have in reefers tanks; it pulls away from the tank a ten fold, it's my opinion and not meant to offend anyone.
I want to be as natural as can be in my aquascaping and it shows with my tanks.
Tunze and seios has created special rocks to allow these monster pumps to be hidden out of site.
I love what the tunze and seio does, I just hate the size of these huge pumps, they simply take away from the visuals of the tank.
If they create a tunze or seio in the future that is mini in size with power, I will be on it and place it in my reef.
As it is, my reefkeeper is pretty amazing with it's programming of the maxis to allow the mixture of intense water.
You can see the movement of the polyps in my SPS and they are happy.
My sand bed has some areas that have solidify but my increase in sandsifters has taken it back to within normal.
With barebottom tanks, I love the SPS look and of course love the amount of currents I see.
But it's not just good currents that make up a tank, it's everything in between as well.
Just my opinion....

P.S
I do have a huge bioload in my small reef, and I've also invested in a great filtration system. I do run Deltec equipment and I'm in the process of adding ozone, just waiting for it to arrive.
My skimmer is rated for up to 175 gallon stocked lightly and 111 gallon stocked heavily, so I'm still way below this recommendation.
My tank is very new only half a year old and I'm still learning, presently I'm learning to fight nitrates as they are my biggest concern.
