Anyone else have lower pH than expected? We find that the pH of the water coming out of this system is between 5.5 and 6 (closer to 6).

Given your results I suspect you are using pH paper or test strips which can be off by a full point or more when testing RO water because the water is so pure. I suggest you get a good digital pH meter to test the water's pH. Remember to test the water in a way that represents normal use. A brand new system will test more acidic than a system that has broken in and is fully pressurized. Using a TDS meter is an indirect way to infer that the system working correctly. Test the water as it leaves the RO membrane and at the RO faucet, and then compare those to the tap water. Remember, the system adds calcium and magnesium minerals which both increase the pH, and increase the TDS.

Raising or lowering the pH will depend on what your current pH is. This unit removes dissolved solids and other impurities to the 0-15 ppm level and brings the pH towards around 7.0, (usually closer to 6.8), but, again it depends on your local water. In theory, if you pH is above 7, it should lower it, if below 6.8, it should raise it. (I wish I lived in Theory! Everything works better there!) I recommend getting a handheld pH meter (available for under $50) and checking it, but with the water in Valparaiso, IN, the pH comes down by about 0.2 to about 7.4, so I have to add a few drops/gallon of sulfuric acid to complete the job, which is OK since we are also a little low in sulfur in the dirt around here.

Low range is 6-7.6 and high range is 7.4-8.8. I don't know anything about the high range's accuracy, but the low range is ridiculously wrong. I checked it against my calibrated pH meter as well as lab standard known pH buffer solutions and it wasn't even close. I don't know how they can sell it.

Be very careful about changing your PH. Do it in little increments . If it's at 7 just leave it at that

None. Save yourself money( a lot ) and find a generic one inch chlorinating tablets . I didn't feel that this system was worth the money. Adding fresh water more frequently is a very cheap way to keep water ph and balance correct.

No: range starts at 6.2-6.5. Get a ph meter, I did and works great. About $20 bucks on Amazon

I wish I could help but I'm not sure about PH fluctuations with this product. Since I have Cichlids that love a high PH I no longer monitor it since my water is high in PH already and they are so hearty.

Youre right, the PH range is 0-14. the picture reads 18.3 because the meter was turned on without being submerged in anything.

If 1ppm solute of unknown identity went in and 59 more came out, I'd bet it's the carbon from the carbon filter. Nothing to worry about. Your water is still absolutely drinkable and mostly pure.

i use distilled water as i believe (do not know) that ph is 7.0 however the tester only lasted for 18 months.

I have well water that is about 7-9, seems like ph stays about the same, it might drop a point. This machine is awesome man it takes my 485 ppm water down to about 12

Somebody skipped out on their Chemistry Class. Acids are pH low and Alkalys are pH high - 7 is neutral. Going from 6.2 to 6.6 is becoming more alkaline - just like the manufacturer promised.

I found the salt strips to be a bit tricky (compared to chlorine etc chemical strips). They take a long time to read, so I was just laying the strip in the water sample. You need to stand the strip up in the container so the bottom is in the water and let it sit. The strip was reading far lower than it should have when laying in the water vs standing up in the water. Perhaps you are having the same issue and it really is higher than 2000ppm. I started out with too much salt because of this as well.

I had a similar issue in a minor way with my first one. It stopped very soon. I figured it was just minerals that weren't secure. No big deal. The minerals are what alkalinizes the water. It's either just a minor flaw in the construction of the filter or some minerals got in there that were too small for it.

justmix 1 half cup of ph powder to 1 gallon and then slowly pour into hydroponic res and flood tank to match ph if thats hoe your set up is if in single buckets then just the res.. i hope this helps out it did me

The manufacturer statement in this regard is "Increases the pH to about 8-10 by adding just 3-4 drops to a glass of water" However, much is dependent on the condition of the water you put the drops into.

Very easy. See previous answers & comments about pH testing. The water tastes very good, though it may be unusual for some because of the alkalinity.
