well I checked the rez temp and it was 67 with the lights off for 2 hrs and just now I checked it again and it is 68 with the lights being on for 1.5 hrs will check it again after the lights have been on for 5 of so hrs to see if it gets any warmer...@reggaerican I would suspect high water temps could be the main cause. Do you know what temp your water is at? Also, I've never run flood and drain, but I can't imagine that problem coming from not enough water. I think 10min per hour is more than enough. But yeah, I've only ever done dwc so not an expert.
