Single Controler Vs. Multicontroler

[Mexican Hermit]

Roger,

What would be the differences between having the following set ups:


1) 2 Streams each hooked up to their own single controler

Vs.

2) 2 Streams hooked up to a multicontroler?

Thanks in advance.

On the single controllers each pump would be independent and the flow would be uncoordinated. On the multicontroller you would be capable of coordinating the flow of both pumps. The pulse timing would be identical. Also, it would be the only way to have tide mode so the pumps take turns running. Two single controllers would give you a chaotic flow.

Can I use the multicontroler with one pump until I save up for another stream?

 

[rvitko]

Yes, you can use just the one pump.

how much heat do they create in the water?

also, with 2 tunze 6100s in a 180 gallon tank the water flow is insane. i was sure you could not keep small fish in there. I was told that because of the stream flow they could be kept. Can anyone shed some light here?

Peace

Next to no heat is produced as they only use 45w(6100) of power and about 10 is conumed outside the aquarium by computer and transformer. I would factor on 1 degree per 100gals. As for the flow and fish- watch the discovery channel the fish are swimming in water that a diver requires a motorized unit to move in. They are more than capable of handling the flow.

I have 4* 6100 in an 180 gallon (6ft) smallest fish are 2 to 3 cm chromis and even with all four streams on they are fine and seem to enjoy the current.

not sure if its ideal for all fish but i think most would be ok

No hope of keeping the sand in place with this setup

Blgreef,

I was wondering more about mushrooms and other corals that call for "low" currents. This is what I am conserned about.
