Question for the Water Doctor:
"I am purchasing a house with well water. As a city dweller and the owner of some large aquariums I would like to do whole house RO. Could someone please reach out to me about a good whole house system/setup? I found this link via Google: https://www.uswatersystems.com/systems/reverse-osmosis/whole-house-reverse-osmosis-systems"Answer from the Water Doctor:
Since Reverse Osmosis removes the largest spectrum of contaminants of any water treatment process (see Filtration Spectrum below), more and more people are turning to whole house reverse osmosis systems. Many people who opt for whole house reverse osmosis mistakenly believe that it will take EVERYTHING out of the water... and while it will, it won't do it for long without proper pretreatment. One thing you need to remember is that reverse osmosis requires proper pre-treatment. A reverse osmosis system with proper pre-treatment will last 10-20 years, while one without proper pre-treatment may be junk in a few months. You may need one or more the following depending upon your specific water chemistry:- Backwashing Carbon Filter to remove organics and chlorine (Chlorine destroys RO membranes)
- Iron and/or Sulfur Removal System (Iron and Sulfur foul membranes)
- Water Softener or Anti-Scalant System (Prevents hard water plugging of membranes)
- Ultraviolet (UV) disinfection if the water has a high bacteria count. If bacteria is high it will foul and plug the membrane.

We are on city water and it is very hard. I use the Enagic Kangen water(anyone interested contact me , I am a registered Pharmacist Pharm D) DrKate.yourbodyiswater.com.
The water from the source is so bad it is 678++ ORP (oxidizing.. rusting.. causing free radicals) my machine struggles to get to ORP of-300 (antioxidant.. free radical scavanger) without any filtering system at all.
We tried RO under sink (with re-mineralization before entering the machine which is needed for the machine to make the water antioxidant and to cause hydrogenated water).. I got my ORP to -600 .. awesome.. but it could not supply enough water.
Then we got a really good charcoal filter and attached it right before entrance into the machine.. got ORP -500+ but got that egg smell (hydrogen sulfide gas). The company could not explain why but said the water is high in chlorine sulfate. I deduced that when the water paced through the machine it used all the hydration which attached to the sulfur (the filter took out the chlorine) and formed hydrogen sulfide gas.
So Question is ... I need a system that will increase my ORP (-) without creating this H2S ?(need to have calcium, magnesium (+ ion) to charge the water ... this can also be accomplished by re-mineralization prior to entrance into the machine). I do want to filter out as much of the junk in the water (nitrates, pharmaceuticals, hopefully fluorine and the other crap they treat our public water with)
Also would like to decrease the hard water throughout whole house. Help please ?

Katherine,
We can fix your water but I need to know what competing contaminants there are and a detailed water analysis is what that requires. This test is for 95 contaminants and accomplishes that:

Does the water from your tap have any odor?

No the tap does not have an odor.
I clicked on link... do I just need the main one or any of the additional ones below?
