A quick question: what cooling pumps do you use?
Mine came with a 2000 l/h (528gph) and I also have a 3000l/h one(792gph) but using a much larger diameter output. I’m a little scared to use the bigger one since I don’t want to blow the glass connectors or a hose from the larger pressure.

I use the stock one with a 5 gallon bucket of water. Works fine in Connecticut (during the winter I leave the pump running when it’s near freezing or below - mine is in the garage.

I have a flow sensor and a standard electronic thermometer stuck thru the bucket lid. Grabbed the thermometer from the kitchen :smiley:

What is the make and model of your stock pumps?

My K40 came with the Dymax PH1200 (1200 LPH/317 GPH). I upgraded to a Hydrofarm AAPW400 (1514 LPH/400 GPH) and now I’m wondering if I should have gone even higher to the 550 GPH model after hearing yours comes stock with 2000 LPH.
