? for 90 gal flow

[pscheel]

Would you go with 2x6000 or 2x6100 for a SPS dominated 90 gal? I will use the multi controller with these. Would I need any other powerheads?

I would get two 6000, you could upgrade them to 6100's later if necessary.

Roger, I already ordered the 6100's. How low can I adjust the flow if I need to? Does the controller adjust the flow or do I adjust it on the pumps? Also what placement do you recommend?

 

[rvitko]

If you have a controller you use the controller and the flow is adjustable down to about 1400gph. If you have no controller you use the driver setting but when a controller is attached the driver has to be at 100% or damage can result.

Thanks Roger! One last question, what do you recommend for the settings on the multi controller for the 2 6100's? In addition to the SPS, I have a hammer, trach and a favia. These will be my only LPS.

Interval 2 gives the longest period between cleaning but Interval 1 may be necessary as 2 6100's running at once may be too much flow, it is largely trial and error.
