In the health sense? It shouldn't matter. You can check if your water is safe to drink it is good to have some minerals in your water. Filtered water is nice and might "taste" better but overall it probably won't make too much of a difference unless you have something strange in your tap.
Playing hard to get can be used as reverse psychology
You might be talking about ice but hard water is sourced from limescale rock and the limescale is in the water and that is what you get in your kettle when you dont filter the hard water.
hard water is which has no ability to lather with soap standard hard water contains 1mg of calcium carbonate in every 1ml of water.
No. Hard water is water with high amounts of dissolved calcium and magnesium.
Hard water contain calcium bicarbonate, magnesium bicarbonate in temporary hard water and calcium/magnesium sulfate in permanent hard water. Soft water contain doesn't contain these substances or only in very limited concentations.
Reverse osmosis water filter do indeed remove hard water minerals - up to 95% of calcium and magnesium ions. These are the ones that cause hard water problems.
Hard Water Raw Water Boiled Water Rain Water Snow Water Filtered Water Soft Water Reverse Osmosis De-ionized Water Distilled Water
If you are refering to a reverse osmosis, it removes desolved solids such as chlorine, floride, hard water deposits such as calcium and lime. It will even remove sodium from the water if you have a water softner. Most R/O's can reject up to 95% of disolved solids.
Needs to be measured. Mostly set by EPA, states, or local municipalities. Can be made less hard be many different processes, such as ion exchange and/or reverse osmosis.
the word osmosis is hard to say.
I would be more worried of the opposite ie. too much nitrate. To the best of my knowledge it would be very hard to get too little nitrate in an Aquarium although by using Reverse Osmosis or Distillation one could possibly make the water incapable of sustaining life.
Jane wished that she could absorb goodness by osmosis, since it was so terribly hard to behave.
The problem with this is that well water is often very hard. 'Hard' water is water that has lots of minerals, like magnesium and calcium, in the form of their salts or carbonates dissolved in it. If soap does not lather easily in your water and if you tend to get white deposits inside kettles, then the well water is probably quite hard. A pet shop or pool shop might be able to test this for you and tell you just how hard your well water is. Most of the tropical fish you're probably interested in keeping do not like hard water; tetras, gouramis, danios, rasboras etc. as well as virtually all catfish are softwater fish and will not thrive in hard water. If you do have hard water, it doesn't mean that you can't keep fish! Goldfish are a notable exception; they are very tolerant of hard water, but they grow far too big to live in your ten gallon tank. Livebearers - guppies, mollies, platys and swordtails - are also good choices for hard water, and would be good choices for a small aquarium and a beginning aquarist, because they're small, colourful and hardy. If your well water is hard, but you really want to keep softwater species, you could consider setting up the tank with 10 parts of rainwater or reverse osmosis water (you can buy a reverse-osmosis machine to remove the minerals from the water) to 1 part of well water. Water with no minerals in it is bad for fish as well, so make sure you include a little bit of well water in the mix. If you're connected to a town water supply, that will probably work as well, although you'll need to add water ager to remove the chlorine from the water (it wil kill fish); any pet store will sell it. However, if your town water supply comes mainly from ground water, it could be just as hard as the well water, so be careful.
because there is no further GEAR in reverse.
ChemicalBecause CHEMICAL change the identity of the substances involved they are hard to reverse.
Reverse is next to first. Lift and push hard left.
