For me, keeping the res temp low was also a diagnostic tool. I had read that if the 'slime' had no smell, was not stalled by low temps, h2o2, and high oxygen, then it is prolly brown slime algae (which is actually a type of blue green algae). H2o2, in my case, did nothing, so sounds like you prolly do indeed have classic root rot.
DM zone recommends water temps of 65-70. If the res will stay 74 or higher, they recommend the strongest dose. I have stopped adding ice and my res temp indeed stays around 75, yet my roots look perfect. I have been adding it at a rate of 1ml per gallon at res change. After 5 or 6 days I add a little booster of about .5ml per gallon or slightly less. I probably should keep my res temp cooler simply because dissolved oxygen and nute uptake is suppose to be optimum at 65ish, but I can't afford a res chiller and adding ice packs every few hours isn't practical.
It will be interesting to see a control bucket added, good luck with that.
