Did not have my water tested , but the water company website annual reports show no violations or high levels of sodium. My 95 PPM is squarely in the middle of the range listed in the report.Does not scare me at all. If you have a water report the only thing to look for would be sodium.
I have a 55 gallon drum that I can fill with water and bubbler to off-gas The chlorine before the water is introduced to the reservoir.It will presumably have some chlorine in it so just let it sit for a day if you care about that. Some do not and are successful.
If you decide to go with automation and RO, you can do auto topoffs at close to 0 ppm with a cheap RO and a float valve like this

$13 for the float, and you can get RO under $100. Something to consider, because you need RO for fog anyhow. You run ultrasonics in straight tap water at a high rate and you will have issues with the minerals in the water.
I have GH powdered pH Down, I will adjust the pH in the 55gal bubbler while it off-gases.For now, that tap water will need some downwards PH correction, but probably has adequate buffering to make running silica optional.
Will do.With GH trio, I'd just add the 95 on top of the chart numbers to start with. So if you are trying to hit 300ppm according to the chart, you will shoot for 400ppm because of the starting point.
I am leaning toward building a DIY RDWC system similar to that offered by PA hydroponicsPA (4 plant RDWC). I'm planning on using the black totes with the yellow tops like you used in your fogoponic thread. I'm a little stuck on what size to use. I kind of like the 12 gallon size for grow totes and the 27 gallon for the reservoir. The tent is 5 by 5 so I could fit as large as 17 gallon grow totes. With the 12 gallon totes be a mistake if I could fit 17s?
One concern is height. I can only fit a 78-in tent in my room so I'm trying to find grow totes that are shorter in height. Hence the 12 gallon idea.
Is there a minimum distance from the bottom of the net pot to the nutrient level?
