I am not familiar with permeate. What is it? Or permeate with what? Is something permeating in or out of the water?
In the U.S. most of the larger metropolitan areas now use chloramine in the water. Aging alone does not dissipate this like it would chlorine. I have found for myself it I treat with Prime (Seachem product) the water in my aging barrels and don't use it in a few days bacteria will start to grow in the barrels defeating the whole purpose of doing a water change. This I why I add the Prime to the tanks just before I refill with the aged water. I also age the water to dispel gasses, settle the PH and raise the temp to just below my tank temps which is also 84 degrees.

Hi Steve, permeate is the pure water that goes through the osmosis membrane.
A very small rest of other foreign particles, may be 5-7% of the total hardness is pasing through it, so so that between 3 and 20 µS/cm can be measured electrically, depending on the quality of the membran, pressure or temperature.

Okay. This is an RO system? Do you still treat for Chlorine?
I am lucky that I don't have to use RO. I have been able to raise fry to adults, have them pair and spawn with eggs that hatch in my local water. I haven't tested for hardness in a few years since I was having no problem with eggs hatching. I have domestics. I think if I had wilds I would have to use RO.
