Suggested Settings for Dual 6100 and 7094 controller

[original-reefland]

Greetings,

I've added a second 6100 pump to my 7094 multi-controller on a 180 gallon tank. The translation in the documentation is horrible. I'm not sure what the best setting is, but this is what I'm looking to do:

Have pump 1 ramp upto 100% while pump 2 slows down to 30%. Then pump 2 ramp upto 100% while pump 1 slows down to 30% Have this cycle repeat with interval between cycles 1-7 minutes.

Thanks for your sugestions.

Hi Rich, their is no way to accomplish this on the 7094. You could do this in 1-7 second intervals or you could have 1 pump off while the other runs 30-100% and have them switch in 1-7 minute intervals. Let me know which you want to do and I'll walk you through it.

Thanks for the quick response. This is as close as I got it so far:

Pulse knob - vertical (pointing upwards).

Channel 1 - top knob 100, lower knob 30.

Channel 2 - top knob 30, lower knob 100.

Interval knob - min.

Interval switch 1-7 min. Mode switch (upper most setting).

I have both pumps connected to Channel 1.

This seems to flip flop between pumps, one pump on other off.

I'm not sure both pumps actually reach 100% during their cycle however.

So you have about 3 seconds between pulses (top and bottom knob). Channel 2 isn't doing anything since no pumps are connected.

It would be better to use the first and fourth sockets with this program that way one pump will be on each program, make sure the switch is on tide mode (two arrows pointing at each other)

Thanks for the suggestion, I'll try it.

Ok, I think I followed your suggestions correctly:

Interval switch is 1-7 minutes, and mode is tidal (upper most setting).

That looks correct, just keep in mind that at night your flow will be 30% and in somecases that is too calm and CO2 will accumulate lowering the pH. Personally I usually do the opposite with top at 30% and bottom at 100% for this reason. The pulsing stops and this is enough of a calm simulation in my opinion.

 

[original-reefland]

30% of two 3175 GPH pumps is still over 2000 GPH, plus the flow of the main return pump. Should be more than enough for a 180 gallon tank.

If I didn't want the pulsing to stop at night, do I just yank the photocell?

 

[rvitko]

In this program only one pump runs at a time. Yes, you would just pull the photocell.
