And is the controller really a value added addition to the tank?

Any opinions are appreciated.

If you are careful about your rockwork and the placment of the 6055s AND you do a 2-minute modification to them you could get away with SPS in the tank.

The modification is simply clipping out and grinding away the lip that is on the inside of the front cover of the 6055. Once it is gone and smoothed out, you'll get a LOT more flow.

Insofar are rockwork and placement is concerned, what you should strive for is open space with water being able to flow all around the rock. Something like "islands" of rock with water flowing around it. In other words, you should not have any rock touching the sides, front or back glass. This maximizes the flow you have in the tank.

Depending on how many 6055s you have, you should set them up the generated "Gyre" flow - think a whirlpool. Do NOT have them aimed at each other if they are on at the same time - only have them pushing in one direction at a time. This way the water will create a whirlpool effect and it will gain momentum over time due to centrifugal force. Done properly your using the flow you have much more efficiently that a traditional setup with powerheads. If you were lucky enough to have purchased a Multicontroller with the 6055s, then you can set up reversing Gyres with the 6055s pointing at each other. Choose Interval 1 on the multicontroller and set the interval for at least half an hour.

I was able to keep SPS with a single Tunze 6000 on a single controller in a 6'x2'x18" tank. The old 6000 doesn't have much more flow than a modded 6055. I currently have a 6055 and a 6100 doing reverse Gyres. When the 6055 is on it pushes all the way across the 6' length of the tank and the flow comes back the other way like it should in a Gyre.

Of course after all is said and done, having one or more of the bigger, badder Tunzes would make keeping SPS a lot easier.
