I'm beginning to think there is way more to this than just air and water. I had both and with temps slightly over 70 the roots suffered. They are now growing quite good and after near death and two months of fighting I've won. Their ready to go in flowering room as soon as I rebuild it 
. Thanks everyone for all the suggestions

Water carries more dissolved oxygen the colder it gets, thus water in the sixties carries much more DO than it does in the seventies. This may be your issue.I'm beginning to think there is way more to this than just air and water. I had both and with temps slightly over 70 the roots suffered.

One of them for sure but the actual temps surrounding the roots when not being sprayed played a roll as well I'm suspecting. Things are still border line with outdoor temps hitting 14c tomorrow my res temps will climb but hopefully stay at around 18-19. All looks real good and actually have raised the light twice in a week

I tired making tea before, it ended in problems.
How much molasses do you use and how much and how often do you add the tea to the rez.
I've read all the threads, I respect your knowledge so coming forest from yourself ensures I don't doubt what I'm reading.

Off the top of my head it's like a cup and a half? But that is for 25 gallons of tea. We follow the og biowar recipe on their website.
The airstone waterfall thing...
Some people like to think that bubbles passing through a water column do not actually oxygenated water. "It's only the ripples on the surface". But ask yourself this question.. how is the air water interface any different between a ripple on the surface and the water around a bubble. Gasses are exchanged.. period.
My issue with the waterfall is this... when the buckets get FULL of roots like ours do, and I mean, packed with roots... where is the waterfall? It's basically just water running down the roots.
Conversely, bubbles are always rising to the surface. No, the water isn't churning when full of roots but you do have air bubbles passing over the roots.
I spent like an hour testing different air stones from the 50 cent blue stones to the $25 micro diffusers.. dude, like millions of tiny bubbles!!!
What my calibrated do meter told me... as long as you have a decent volume of air, it doesn't make one damn bit of differnece.
Lastly, water temps above 70.. or even 68 really is just clown town shit. Problems or not, it's mickey mouse and disaster WILL strike.
Happy growing

That's why I think I have great luck with my flooded setups, the water shoots out of the bottom res and splashes against the lid with a pretty good force, it's pretty splashy in there lol. I've been doing the same thing for three years and one season into the sprayers and a major war breaks out. Everything was the same except the setup. So yes obviously the chiller was a great investment as it cured what was a basically dead run but I'm still baffled as to why this run after probably 20 runs I got this shit. Is it possible the fountain thing added that much more DO? Perhaps a DO meter would be a cool meter to play with . Also I found with the fountain deal, I had better growth with pump running 24/7 once roots were established.

everywhere i've read they recommend water temps of around 70 to 72 when using bacteria in the form of tea? i see you're temps are much lowerHard to say. I had a "desperate" rdwc run several years back and nuked it with physian 20. Then benies.. the plants looked fine but didn't grow for like 3 weeks.
Look dude. Tystk and I do this shit for a living. And I'm not taking oh wow.. 10k watts. We are talking $150k + commercial build outs. My overhead is 20k a month so when she goes wrong.. it HURTS. It hurts REAL bad.
I currently have 96 5' tall plants, 55 2' plants and 55 small plants in DWC.
1. We never ever never let the water get above 67, ever. Typically it's 63-65.
2. We add 5 gallons of beneficial tea to our 200 gallon reservoirs twice a week.
3. We never use any kind of coco or dirt or whatever... it ALL has bugs in it.
4. New airstones every round. Yes, we buy 50 air stones a month
I have not seen root rot in about a year.

^^^^ Well I was running 71-72 with beanies and almost lost the whole shabang, just saying .

72 is warm enough for all kinds of problems. The only time these temps make sense in water culture is with aquaponics, fish culture.
The problem with bennies in RDWC isn't temperature, it's living space. They need some kind of structure. Without it, you just add more on a regular basis to replace them as they die.
I've heard of people creating 'biofilters' made of things like plastic dish scrubbing pads (non detergent, obviously! ) placed inline somewhere, I don't know if that turned out to be viable.
Personally, my favorite range is 61-66.

Roots are fully recovered. Plants doing fine btw. Should have done the chiller thing from the start. Starting to work on a DIY compressor unit, should be ready by spring lol.

A moving bio-matter filter works good for breaking down larger amounts of debris, including algae and plant debris. Prevention would be the better choice but I don't see why it wouldn't be a good idea in Hydroponics. Its normally used in conjunction with Aquaculture, but would definitely work in this case. Here's an easy DIY version..

I never said it wouldn't work; I said I haven't seen it done successfully for RDWC.

That's cool. I just thought I'd throw an idea in that might not have been thought of. In a month or so, I'll throw up a video with a moving biofilter with just DWC for the test. I use one now, in my aquaponic, Ebb in Flow, Aero, and NFT. Problem is, without a continuous supply, the Nitrogen might be thinned out too much.

Just wondering if an enzyme would be a good addition? Does it work better to break down the organic matter or are beanies and enzymes one and the same, sorry for the newb question, just tired of reading lol.

Enzymes in DWC/RDWC = BAD JUJU.
