Pump placement suggestions

[Mark Bianco]

I finally got my new to me 220gl 72" L X 24" W x 29" T It is an AllGlass with dual overflows they are on the back wall and start about 10" from each end. This tank will be minalistic this time (Not a fruit stand) and I am thinking of doing a foam rock back wall. So if you reccomend placement of the pumps on the back wall by the ends I need to leave room. Most corals and clams will be going on the bottom, but I will have some SPS about 1/2 way up.

Where would you reccomend placmet of each pump, and what flow nozzle should I use on each?

Thanks in advance
Mark

Regarding flow housing, the focused housing will hit the far end and bounce back, the wide flow housing should reach all the way across but the flow will be reduced on the far end. You could do back or side wall, I would want them as far over as possible to reduce dead spots on the ends, especially with the wide flow, the velocity of the flow will be fairly low after 5ft. I won't aim them to hit the front about 4-5 ft away, almost to the far diagonal corner.

Roger,
I apoligize I did not mention the pumps I will be using are 4 6105 pumps I am not sure if that will make a difference or not.

So if I am understanding correctly I would place pump #1 about 1/3 up from the bottom on the right side back corner and pump #2 about 2/3 up from the bottom in the back right side corner setup as master's Then pumps # 3 and #4 the same place except on the left side set up as slave's and run them in the inverse mode. using the Y adapter
(7092.340) and the 7092.000 controller. Or would I just be better off ordering the 7096.000 controller.

My goal is to have strong flow from left to right for a couple of seconds them strong flow from right to left. for a couple of seconds. Sort of a small wave from left to right then a small wave from right to left...

I hope I did not confuse
Mark

The 7092 cannot do that, it only can pulse the pumps (all on and pulsing between two speeds) or create a wave. You would need the 7096, 4 pumps will be plenty. The Y adapter would not be needed. With 4 pumps there are a lot of options, you could use sequential with all pumps parallel on the back wall, you could also use Interval mode with 2 pumps on one side and after so many minutes or hours they switch. I might start with 2 pumps, in many cases this will be plenty, I can't think of any set up besides a fully loaded SPS tank needing 4 pumps in this gallonage. I would have one in each back corner, aimed to hit the front 4-5 ft away. If you use 4 pumps, sequential or 2 on each side in interval is likely the better bet.
