so if I used a tds meter on my ro water and the results come out worse than it should. should I be concerned? A plumber says its fine unless water tas

If your system is new, there could be some residual total dissolved solids (like carbon from the filter) in the system that will give you a higher reading temporarily, but your plumber is right about the water taste being the most important thing for now. The awful truth is that high efficiency RO systems cost over $1,000, so while we are protecting ourselves with the GE system, there are many better systems on the market. I have the GE system and am looking for a replacement because periodically (about every six months) the system clogs and causes water to flow out of the vent line and onto my counter. I have to turn off the water supply from the tap, disconnect the vent line and blow it out with air. For now, the GE System will be sufficient, but I'm looking for something better.

Not with this unit its performance is based on ideal conditions and at peak, meaning totally great water to begin with, and only within the first 48 hours will you see these filters preform as advertised.

Use a TDS meter to tell when the membrane needs changing. When the TDS starts to go up its time to change. I typically get 18 months per membrane, but our water is notoriously clean. I only use my RO/DI system for making water for my reef tank.

You have to calibrate it. It was beyond me. But i had a friend who'd done well in chemistry. He was unsuccessful in getting a reading that made sense, but I blame that more on him, than the reader. I would look for a pre-calibrated meter for someone with limited tech skills. i needed it to test PH in pond water. I have several mud ponds. The PH is a little different in each of them.

None of the cartridge filters remove TDS. If you want that, you need reverse osmosis. It's a choice. Some people don't want to remove minerals, just organics and lead, some do.

FROM HM DIGITAL: Not for the majority of applications. The TDS-EZ has been factory calibrated to 342 ppm NaCl, which is suitable for most applications, including the majority of drinking water in the United States. However, it is possible you may wish to re-calibrate depending upon your needs, such as if you are testing in a much higher range (for example, over 1000 ppm). All TDS meters will retain their calibration for about two years, unless they are dropped, left in the heat, etc., in which case they may need to be re-calibrated.

that all depends on what your tds is prior to adding the fertilizer u can get a tds meter on amazon for 15 to 20 bux so I would definitely get 1 however tap water is usually no problem

On their website it says;"Q. Does the ZeroWater filter remove Fluoride?A. ZeroWater filters are not certified for the reduction of fluoride however fluoride is an inorganic compound. The TDS meter is designed to detect inorganic compounds. Fluoride levels in water are usually around 2 to 4 ppm, which will show up on the meter as 002 to 004. So when filtered water reads 000 it is not likely that fluoride is present in water."So basically if the water meter reads zero there would not any measurable amount of fluoride in the water.

Im the last person to answer this one. Both boxes i purchased tested on distilled water, tap water and my spit the same reading. i never could get the strips to change from the same reading. I do know under normal testing (other strips i did notice a change when water was tested).

After about a year of operation on my filter I noticed some water at the bottom of the gauge...pulled it out...shook the water out...after awhile it returned...shortly later the gauge stopped working altogether (would not register...just stayed at 0)....so I would say, from my experience at least, water in the gauge is a sign that the gauge is getting ready to die.

Did you ever do this test? I am very interested to know if the residue comes from the water or your feet. I have a water distiller and I can get a residue left from our tap water (without putting my feet in it).

If RO water is similar to the stuff that flows from my faucets, then yes. If RO has lumps in it, then I'd suggest pre-filtering with cheese cloth.

The test strip you are using is not accurate/sterile enough to accurately test the PH of water...One thing that everyone should know about these (and other) pH test strips is that they work based on the TDS (total dissolved solids) that are present in the water you are testing. If you are trying to test a true distilled water (with nothing in it, no TDS) the strips won't be effective and I'd recommend you use a test drop for the water sample.

A TDS Meter tests the number of particles in the water, not the type of particle nor the chemical composition of the particles. A TDS Meter is NOT the same as a hardness test strip - Water hardness is caused almost entirely by calcium and magnesium ions, while by its very nature a water softener is designed to replace hardness with sodium. It is called a one for one ionic exchange. For example if you have 200 PPM of hardness it will be converted to at least 200 PPM of sodium. Our tests show you can expect an additional 20% in residual salt and sodium after that exchange in most cases. In other words 200 PPM of hardness will usually be replaced with 240 PPM of sodium. Thus the TDS Meter will show an increase in the parts per million due to the increase in sodium which is ignored by the Test Strips. That would explain why PPM is higher on the softened water than the original hard water..

I used it all last year and did not have a problem. but my water is filtered, I think if you have too much calcification in your water it will be a problem. I am on well water. Bottom line it depends on your water quality.

Anthony, I can't answer that because I had a plumber hook it up. he did not mention any problem to that affect. Unfortunately, he lost the documentation and after many tries and almost 2 years, I have yet to get a copy. Maybe you can help me by sending me a copy? the temp gauge quit and I have no idea on how to change/fix it or what the warranty is because I have no documentation.Mitch

Yes. It removes everything. It reduces TDS to zero. Be aware that this water is NOT suitable for drinking. It is intended for special decontamination situations such as saltwater aquariums.
