HydroFlow s38
Our house is a new copper construction with water flowing through the system for about two weeks prior to installing the HydroFlow, the hardness is 250 ppm, alkalinity 240 ppm, and pH 7. After a day with the HydroFlow, the dryness of skin and itchiness after a shower has been reduced and hair seems fluffier.

Finally! got my hands on a Pearl Plus. It's installed and running! and I'm sure it will perform as nicely as my s38 unit does. If it doesn't I'll come back and change my review
Very Pleased
I live in Utah and I have really hard water. I've always wanted to try one of these out and finally got the courage to give it a go. I'm so glad I did. I don't see any signs of scale and my water isn't slimy from the salt. Works better than I thought it would.,
Installed this 7 months ago and I have not had a scale issue anywhere. Very pleased with the results.
Worked great
I have very hard water and this little device stopped all the problems that scale was causing. I would give 5 stars but I gave it 4 because of price.
very happy
Purchased this to reduce scale problems in the house. It woks very well. If something changes I'll repost
I simply wanted to get rid of my water softener. This seems to work.
3 month review
We have very hard water from a well. Thank goodness it's the only real issue we have with our well water. I installed this on my cold pipe going into my hot water tank as per the instructions. It is definitely doing something to the scale but it's not making it go away. Instead, we are getting a lot of this white powdery stuff appearing in our drains and aerators. I called the company and they explained that is what its supposed to do. Once it's done descaling the system it should stop. I gave it 4 stars and will raise to 5 when it stops.
Still shows as hard water
I live in a hard water area and I will say that this device does keep the scale from sticking to things. It however doesn't lower the number of solids in my water. My TDS meter still shows the same number.

Worked perfectly
I don't live in an area that has ridiculously hard water. I believe we have a hardness of 125 ppm. This is why it worked so perfectly. Hard water is merely a nuisance and it's not at a level where I need a water softener plus I don't want to add sodium to my water. I simply want the annoying staining to stop. After 2 weeks of being installed, it did its magic. The hard scale deposits went away and the ones that were left over were easily wiped away. So glad I get to keep the healthy calcium in my water and not have the problems. Well worth the money. I had previously tried a similar device that used magnets, It did nothing to help with the problems we had.
