Help me select the right Turbelle

[Fred0860]

I am rebuilding my 130 gallon (61 x 21 x 24) reef tank, which will be SPS dominant. I want to get a Turbelle strong enough to get most of that water moving and create a gyre. I am thinking to place a Turbelle on each side panel, facing each other, on an alternative long cycle (3h or more) to reverse the gyre.

After reading this forum and several other sources, I am still not sure which is the best match for this purpose: 6105, 6155, or 6255? Last year's article from Advanced Aquarist leads me to believe that the 6155 might be the right choice, and that the 6255 could actually be counter-productive. Would you agree with this?

Note that I would prefer not having the pump run at 100%, so I could increase the flow at a later point or create a storm effect from time to time.

As a side question: Roger mentioned the 6255 need cleaning every couple of month vs generally 4-6 for the 6105. How does the 6155 compare in this regard?

Thank you.

The 6255 is particularly high maintenance as the spaces are tighter due to extra reinforcement and bigger magnet and the coil runs hotter. The 6155 is closer to the 6105 in maintenance needs. A 6105 is fairly strong for a 130 and that would be what I would use (2 of them), the 6155 is likely overkill, I generally am comfortable with 2 6105's only on tanks up to 180/210 gallons. The 6105 also is more versatile in that it includes two front housings and if you needed the more focused housing you could use it.
