Questions..

[Ed Hahn]

I have a 1/4 horse chiller, 450 watts of heaters, two external pumps which are a dolphin 2100 and Sequence 5800. I am also buying a fluidized calcium Reactor that will run 8 hours a day. I am planning on upgrading to 2-400 watt Metal Halides to run these 12 hours a day. I was hoping to time a Kalk reactor to run at night when my lights were shut off.

Will your controller keep my temperature stable with in 4 degrees and run all my tools with out any problems in a accurate time sequence?
Thanks in Advance,
Ed Hahn

Ed,
Since nobody has responded to you, I'll add my 2 cents. I have read that the Reefkeeper will support 1500 watts of equipment. I assume that means 1500 watts that are turned on at the same time. I would say that your load would be pushing this when the lights were both on and the heater or chiller was on (along with the pumps and other equipment).

Hopefully, DA will respond with a more definitive answer.

Ed,

The best way to figure this out is to think in terms of current (amps), not power (Watts). There is a 6A max limit on any one channel and a 15A max for the whole system.

You will want to look at each device and see what the max current is for it (be conservative). Hope this helps (sorry for the delay).
