Tds Ppm
High TDS reading on Reef Tank?
My 24 gal tank is cycling right now with live rocks and live sand. My well water has a reading of 110 PPM and after it goes through the RO/DI unit it has a reading of 70ppm. When i do a tds reading on my tank it has a reading of 700x18 ppm . IS THIS RIGHT? i have a HM DUAL DIGITAL TDS READING METER
One summer i worked at one of those "students needed for part time work" things that are posted at every college campus. It turned out that we went door to door trying to sell people water softeners by shocking them with high TDS.
The problem is that just having a high TDS does not necessarily mean that the solids are bad for your aquarium (of course TDS stands for "total dissolved solids") it just means that there is stuff other than water in your water.
TDS meters are notoriously inaccurate and even if you do get one that is accurate it must be sent in yearly to be recallibrated if you want "perfect" readings. This being said i would go out and buy a bottle of Aquafina water, the only water that i know of that always has a TDS of 0 and make sure that my TDS meter was accurate. Also when you clean your TDS meter after use i would just pour a little Aquafina on it every time after testing to make sure none of the residual solids in the water that you were testing dried on your meter.
I know that people do TDS readings on tanks, i personally dont since i cant afford to keep one properly callibrated and honestly i dont think it does much good (just my opinion though)
As to your reading out the back of your RO/DI i think that this is pretty poor depending on how much stuff is in your well water to begin with. Here in the high plains of texas you usually get between 700 and 800 tds from well, with a good membrane and 5 stage ro you can get your tds under 100 and using real good di's you can get your tds down to around 1 ppm but you have to replace your resin often.
What i would do if i were you is test my water for phosphates and metals and of course alkalinity, if all of these came back negative, i would just not worry about TDS, i have a buddy that uses straight well water for his mushroom/ leather tank and has no problem except the occasional diatom bloom (with TDS of 720 according to his meter that is 3 years old and has never been callibrated,) he does however use LFS bought water for his zoa, frag, and sps tanks.

HM Digital ZT2 Basic TDS Meter $40.79 The ZT2 Is highly efficient and accurate due to its advanced microprocessor technology. The ZT2 Tests for inorganic materials commonly found in drinking water. The ZT2 May be used on all types of water except hot water. The ZT2 Is an economy model that is ideal for endusers and retail products. The HM Digital ZT2 has an autooff function: the meter shuts off automatically after 10 minutes of nonuse to conserve batteries. The HM Digital ZT2 has a measurement range: 0999 ppm. The ZT2 has a large and easytoread LCD screen. The ZT2 is factory calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a miniscrewdriver. The EPA Secondary Regulations recommend a maximum contamination level (MCL) of 500mg/liter (500 parts per million (ppm)) for Total Dissolved Solids. Many water supplies exceed this TDS level. When TDS levels exceed 1000mg/L it is usually considered unfit for human use. After reverse osmosis distillation deionization microfiltration the TDS level should be less than 50 ppm. Test your incoming water supply and the treated water to determine how much Total Dissolved Solids are being removed from the water. At least 80 of the TDS in your water should be removed. If the TDS rejection is less than 80 it is time to change your RO membrane. Range: 0 999 ppm (mg/L). Resolution: 1 ppm (0999 ppm). Accuracy: +/ 3. Conversion Factor: NaCl (avg. 0.5). Power source: 2 x 1.5V button cell batteries (included) (357A). Battery life: Approx. 1000 hours of usage. Dimensions: 14 x 2.3 x 1.5 cm (5.5 x 0.9 x 0.75 ). |

Back to Grow Basics PPM-TDS-PH What......
TDS in our well water is 750 PPM. I should install RO System or Ultra filteration System or just a plain UV.?
can the TDS level be reduced as the water level increased after rain. we have municipal water connection also. overhead tank has supply from both sources. TDS level could be change as and when municipal water supply increased because of the low TDS level in municipal water and high TDS level in well water. how much amount of TDS be reduced by using RO and Ultra Filteration System. Please Advise.
a small amount
