Hi, I am selling the chiller above. The chiller was bought on June and only on for 24 hrs to make sure it is working well. Reason for selling: uprading to Artica 1/4 as I din't calculate the water volume correctly. HC300 good enough for a standard 3ft, but I forgot I have a 3.5ft sump . Altough the chiller could still maintain the temperature I set, it takes longer than usual to chill, thus decided to upgrade. Condition 10/10, as good as brand new! Going at $300 firm. Thanks
