Coralife Aqua Chill

Johnny Reefer · #1 02-01-2007, 02:41 AM

I fired up my chiller about 4 weeks ago and I'm a bit puzzled. The water temp was at about 82F. I set the chiller for 79F with a 2 degree differential. For the first evening the chiller kicked on and off a number of times and pulled the temp down to 79F. (Nice and quiet, BTW). But here's the thing....I haven't heard it kick in since, and yet the tank temp remains 78-79F.

Just wondering if anyone else has had a similar experience with a Coralife chiller....or any chiller, for that matter. I also have a 300W heater running off the chiller.

Any ideas?

Thanx much,

Is the temp you're getting the reading on the chiller or a thermometer? You may have to check the temp with a normal thermometer and then "calibrate" the chiller to that temperature. I know my chiller was off by a degree or so when I first got it.

Maybe the heater has a thermostat that is a bit off. Did you notice if your heater was running off and on before (when it shouldn't have)? Now that the chiller thermostat is controling the heater, maybe that fixed the problem..??

Just thinking out loud here..

Both. Actually three readings. The chiller reads 78/79....I have a pinpoint probe in the sump that is at 78.5....and I have a pinpoint probe in the display tank that reads 77.5.

I should also mention that in addition to the 300W heater off the chiller I have a 200W heater plugged in as a heater normally would. Whenever I look I never see the 300W heater on and the 200W heater is always on. Both are in the sump.

It's weird. I guess it's doing the job but I never hear it. I'd like to hear the chiller kick in just once, just so I know it's alive.

Cheers,
