Chiller

[pop]

I have a resun CL 650 and runs a 2000litre pump from sump 3 *1.5*1.5 to main tank 3*1.5*1.5.

I estimated that the chiller will kick in about every 1.5 hr for about 50mins. I set the temperature to 27 degree. Is the flow rate ok or too slow?

the flowrate is too fast IMO.....1000lph shld be more den enough...

if this dosent help, ur chiller shld require servicing...

also, ur number of equipments does contribute to the transmission of heat...

If i would to reduce to 1000lph plus head lost from sump to tank.. i may be getting even lesser flow rate to the tank... wouldn't it be less effective? Cos i am not really sure about other reefers' chiller kick in frequency... Just wanted to know if mine is normal..

I'm using a Resun CL650 also with temp set to 27C. My tank is 3'x2'x2' with a 2'x1.5' sump. I'm using an Eheim 1262 to pump from sump thru chiller to main tank. I'm suffering plenty of headloss, I guess my final flowrate is somewhere 2000L/hr or less. My chiller kicks in maybe every 2-3 hrs and runs for 45-60 mins on hot days. On cool days it kicks in maybe every 5-6 hrs and runs for 45 mins.
