    Hi folks,:;hi1
    I have a doubt whether I can use RO purified drinking water in the tank or not?
    Till now I'm using my ground water which is brackish and it leaves salt layer in my tank glass.
    My fishes are doing good in current water itself but Im planning to use this RO water in order to eradicate the layer formation.

    Kindly advice the RO which we use for drinking purpose and the aquarium RO process is same or different.

    R/O is R/O, whether for drinking or aquarium use. Aquarium units are just higher production units, as more water is needed for aquariums than for drinking. I use R/O from my aquarium unit as drinking water, as well.

    Drinking RO (purified) water itself is bad for anyone, it will flush minerals from your body causing electrolytic imbalance, avitaminosis and anemia the cause of more serious health issues. I do not even know why in US , the FDA do not mandate purified water bottles to be labeled as "not for direct drinking" or something like that.
    Same for use in fish tanks, R/O water cam only be used when properly reconditioned wihich include re-mineralization and enrichment with required elements to bring TDS at least above 1n.

    That's all quite ridiculous. All the things you listed will happen if one drinks too much water of any kind. R/O units are frequently sold specifically for drinking water use.

    I use R/O for drinking water all the time.None of the health problems you suggest have happened. Most of the things you say will be flushed out are replenished by a good diet. I've mentioned my use of R/O to my doctor, he says there's nothing wrong with it.

    Do you have a source for this information?

    His reasoning was logical medically speaking, but also medically incorrect.

    "As for the relative potability of the pure waters, the difference in waters is very small. There is no adverse health affect from drinking distilled or deionized water. Deionized water tastes kind of bland & somewhat insipid, and distilled water has no taste at all. Some people get used to these qualities & drink them all the time. In either case, the taste is improved by aeration--if you shake the pure waters up with some air, the taste improves. The taste of any given water is largely imparted by the various mineral components; many of the drinking waters on the market today are, in fact, purified tap water to which minerals have been added (Avalon, etc). By law, drinking waters can not have more than 1000 parts per million of dissolved solids, so when you get down to the analysis of most available waters, there really isn't much difference between tap water, mineral water, or purified waters (no nutritional difference at all between any of them!) As far as the health issue is concerned, it is true, water is hypotonic to cells & will destroy them. However, tap water is also hypotonic to cells. Your skin & stomach & intestinal linings are perfectly suited for thriving in and processing water. If you were to inject water into your blood, cells would die. If you cut your skin & wash the wound, the exposed cells do die. Fortunately, the fats that lyse out of the exposed wound quickly makes the wound less susceptible to water damage. Any ultrapure water you drink will quickly dissolve some saliva from your mouth--as soon as it has dissolved few parts per million of any substance, it is no longer ultrapure anyway. If it is a concern & all you have to drink is ultrapure water, you can stir the water with a metal stainless spoon or your finger first & it will magically transform itself from ultrapure water to just water."

    Medically incorrect? By which standards? By yours? By those defined by fda? Pardon me but with largest vs global scale problem with disfunctions among society including obesity, diabetes and overall metabilism issues in this country, there have verry little to argue about in that matter.

    And when did you last time did your blood check panel? Even if you did, have you ever seen results? And do you understand them?

    I am not going to argue about this neither bring up facts of so many examples of food products approved for sale which consumption leads to serious illness in long run. Including bottled RO water for use daily for drinking. Good luck with that.

    I worked as a CST/FA for two years assisting in vascular surgery.

    If you lived STRICTLY on RO water, no foods, sure you'd demineralize your body in no time. If you eat a balanced diet as most people do and drink RO water as opposed to tap water you'd see absolutely no difference of any kind.

    Exactly, one excludes the other. With all do respect, you are living in a dream world, my friend. Knock...knock. All the best!

    Hi, you can use RO water but you will need to remineralize it for your fish as they will not live long with water that has a TDS near 0. Plus there is no stability for PH in RO water. Depending on your fish and their hardness requirements, all your may need is some crushed coral, limestone or aragonite in your tank. Otherwise I'd suggest a buffer and GH replenishment that includes calcium and magnesium salts.
    You could just use half tap and half RO.

    What kind of fish do you have?
