68-72 above 75 promotes algae

Anything under 70 degrees and you are good to go.. Try not go lower than high 50's..

The cooler your reservoir, the less problems you will have. I have run my solution in the 50s for months with no discernible difference in growth.

Me too I have gotten good results even with temps in the 53 degree range.

86F for optimal growth. Lower for less risk. I keep mine around 68-70.
Colder holds more dissolved oxygen and fights the nasties. Warmer provides for more productive growth, with a greater risk for problems.
DO is irrelevant anyway if you put enough direct aeration, and bacteria/algae can be prevented with proper res maintenance and teas or sterilization, though an outbreak will always be more likely in warmer temps.

Keep your tank changes weekly or bi weekly 72 is fine. I'm running 73. Chiller isn't needed for 3 degrees. If your worried about it freeze a few 2L bottles of water. Change them out once or twice a day. But 60-69 is the best range. To cold and non purple buds can turn purple. My MK will stain your hands purple when I get under 60. But might do it this grow. Been ask for purp. Just haven't gotten seeds yet.

I just picked up a 3 gallon rubbermaid cooler for DWC and it is amazing. One 20 oz bottle of ice keeps it below 70* F for 12 hours with ambient temps getting as high as 90 at times.
