So the cold water did not prevent your root rot nor even slow it down. That happens more often than you think contrary to popular belief about chillers and cold water. Chlorine, chloramine and hydrogen peroxide might kill lots of stuff if the cold water isn’t working. Ozone works great and will eliminate any stinky odors too.
Hope is always the buzzword… first always chill the water and hope you can prevent the fungal outbreak, then hope you don’t catch a dose of the fungi, when that fails then hope you can cure the disease with chemicals when you catch it and then the ultimate firefight is on. The fungal disease is ubiquitous, just waiting for the right opportunity.
The cause of the root rot infestation simple, the grower in charge failed to keep the plants and beneficial microbes healthy, the plant became stressed and released stress chemicals, the stress chemical signal the fungi to come and eat… and they came and they feast on rotting plant tissue, they multiply and they colonize… the BOD and COD increase dramatically causing “low oxygen” and more cellular death and dying. Now you have caught yourself a full blown dose of the dreaded root rot disease.
Fungi always wait patiently for the plant to release stress chemicals which is the signal to colonize and feast on the dead and dying plant tissue and multiply. They do the same thing with a dead/dying humans too. They are like a turkey buzzard or Cara-Cara when these birds smell chemicals releases by death and rotting flesh… they congregate and many come and eat, it’s fiesta time.
Of course disinfecting a hydroponic system is a challenge and not sterilization by any stretch of the imagination. You might review “aseptic techniques” as sterilization may be a far reach for most hobbyist.
Disinfecting equipment with Consan (Dimethyl Benzyl Ammonium Chlorides 9%) is an another option when your whole system is seriously contaminated http://www.solutionsstores.com/consan-triple-action-20-fungicide
And of course, if all the chemicals fail and you catch another dose, get rid of the contaminated equipment and start over fresh with clean equipment.

. You sure are a giant douche and now it would seem a giant rat as well. Your like the pimple on my ass that I think is gone and then ouch it's back.
. Got a 22' Princecraft deck boat now 
. You should move along and let's us real growers discuss growing.
