Hey guys I've got a 5gal dwc bucket and I've been struggling to keep my water temps consistently below 70f. I've got my bucket sitting in a tub that I fill with ice/frozen water bottles when I wake up and also when I get home from work. By those times the ice is melted and temps back up so I feel like what I'm doing is a waste xD I've heard people talking about water chillers n such but never seen what exactly I need to get to make one! I see chillers on amazon but they just look like a plastic box that I need to add parts to chill water how I want to. ?? Lol any help like parts lists would be awesome! Or even a good all in one kit! Thanks in advance guys!
