Enter the water hardness value, in parts per million, into the calculator. Double-check the entry to ensure that it is accurate. Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon. For example, say...
Mineral water: Mineral water is spring water that has at least 250 parts per million (ppm) of total dissolved solids (TDS) in it. These "dissolved solids" are minerals like calcium, magnesium, sodium and potassium, and they must be present in the water at the source, not added later. ...
What Is A TDS Meter? A TDS meter is a tool used to measure ppm. Technically, you measure the TDS of water, and you measure it in ppm. However, most people just skip over TDS and use ppm for both terms. There are many TDS meters of varying cost and abilities; some also measure te...
pH level (how acidic your water is) If you find that your pool water's chemistry is so out of balance that it's untreatable, you may have to drain your pool. If your water sample's TDS is 1500 ppm over the TDS of the water from your fill location, you should drain your pool. ...

It is also worth mentioning that many varieties of algae feed off nitrates in the water. Many algaes use nitrates as a food source. In this case, I recommend keeping the nitrate levels below 10 ppm. This helps deprive the algae of its food source, making it easier to eradicate. FishLab...
This is a result of three primary elements: How many minerals are present? How readily do they dissolve in water? How long water is in contact with the mineral source in the earth? Effects of TDS Level TDS is expressed in parts per million (PPM) (ppm). Between 50 to 300 ppm is the...
