Tank estimated volume: 380l (max) 3ft x2.5x2.8 tank with 3 ft sump that is 1/3 lvl (same pump, same chiller location)
I set my new artica 1/4 chiller to kick in 28DC and cut off at 27DC
Hmm interestingly... was initially using a 1/2hp chiller (will not state brand cos might offend ppl).. set it to the same as above.. and it took 1.5-2hrs to chill down 1 DC and would kick in again 1.5hrs or earlier after a while (had it serviced regularly)...
After switching to artica... it take 30-40min to chill (somewat longer at nite) and wont kick in 2-2.5hrs (2hrs during lights on) later...
this is wat i gathered from observing it closely as its a new setup Not sure about the wattage either uses... but was really impressed after switching..
