How do y’all keep your water temperature down with out using a $$chiller?
Dwc mine is at 79 degrees. From what I’ve read I’m in the danger zone
Frozen water bottles about the only alternative to a chiller. 79 is pretty high, you should shoot for 68f.
If you could get into low 70’s would probably be able to get by with just pumping a ton of air in and hydroguard.

The ice cold water bottle won’t shock the roots if contact is made?
So set up a flush bucket and run your water threw it. Have you ice in it is how I do mine worked great.it will add a pump but it works

It may a little. Should only be a small portion of your roots if any though. How big is your res?
Ultimately the only thing that works is a chiller. You can buy one or make one if you’re handy. Buying one; get one rated for salt water.
Temps in mid 70’s and higher reduce available O in the solution and greatly increase the risk (certainty!) of getting root rot (pythium).
