I'm looking to by a RO/DI unit, where can I buy a unit for drinking water and marine water. Or should I just stick with a unit for the marine tank

as far as I've done research, the drinking portion can be removed before it goes thru the DI resin and the water for the Tank you would take after the DI resin. I still cannot see the logic behind drinking it after or before the DI resin, but as mentioned before, just to be 100% safe drink it before it goes thru the resin.

a simple T-piece in the pipework and a tap or reservoir tank to store the water temporarily.

As far as I know it is not good drinking RO water straight from the unit. Before or after DI. One can become sick. Not 100% sure about the facts but I know when I buy water from the healthshop were I stay they add minerals back into the water.

Dexter has a point...but you can overcome that buy adding a minerilizing cartrige in the drinking water section...

Drinking RO that is depleted of all minerals is not good for your health....also some interesting studies done showing how cooking in RO water even depletes the food of minerals and vitamins etc..

Yes,
It is not recommended to drink RO water. It'll remove the minerals from your body...

Rather use a domestic RO unit for drinking etc.

Think the whole drinking ro depletes your body of minerals is a bit of media hype . How many minerals do we really get from water compared to what we take in with food?

Demin Water will deplete your system of minerals, But its not going to happen instantly after drinking one Glass of water! It will however happen with continuously drinking demin Water!

It wont add any to your system, but it isnt going to magically suck them out of your body. Still trying to find a valid article that states how much water i need to drink to get my daily dose of minerals.

A Few Disadvantages

You might be interested to know that reverse osmosis was actually developed as a water treatment method over 40 years ago. The process was used primarily to de-salinate water.

The following are three of the main disadvantages of drinking R.O. water:

1. The water is demineralized.

Since most mineral particles (including sodium, calcium, magnesium, magnesium, and iron) are larger than water molecules, they are removed by the semi-permeable membrane of the R.O. system.

Even though you may find some contradictory information online about the health benefits of reverse osmosis water, I am convinced that drinking de-mineralized water is not healthy.

The World Health Organization conducted a study that revealed some of the health risks associated with drinking demineralized water.

Just a few of the risks include gastrointestinal problems, bone density issues, joint conditions, and cardiovascular disease. (See reference below to review the WHO study online.)

Removing the naturally occurring minerals also leaves the water tasteless. Many people thus have to add liquid minerals to their R.O. water to improve the taste.

can we get to a level of seriousness here? Water is H20, the body needs H20 to do certain functions.

Please advise what Minerals the clouds put into rain water...

I am however aware of minerals being added by the rock to ground water. But please don't confuse this with water we drink and food we eat.

There are also 2 different types of minerals organic and inorganic, organic minerals are cheaper to produce but have very little uptake into the body.

We obtain the minerals we need from the Food we eat, not from what we drink guys.

from the first article:

Commercially and municipally demineralized water is commonly "stabilized" by adding minerals and trace elements after processing. The purpose for this is not to replace essential nutrients, it is to make water taste or smell better, or make it more stable or less corrosive for use in various industrial processes. If improved health was the reason for re mineralization, the choices and forms of minerals (and their ratios) would be very different. Households who use demineralization on their drinking water to purify it seldom, if ever, do anything to remineralize it, so many people are now drinking demineralized water.

your second article:

C. Use only a carbon filter or other natural filter. Do not use a multi-stage filter to remove fluoride, lead, etc. These damage the water in some subtle way, in my experience.


can we put this to rest just yet or would you like to post some more.

Lol, you are taking it out of context buddy,
also they are not talking about our local municipalities.

Water purification involves processing water to remove unwanted contaminants (also referred to as demineralization). Water demineralization removes health supporting minerals that are found naturally in water too. Most water re mineralization efforts are done strictly for commercial or industrial purposes. A World Health Organization report, ‘Health Risks From Drinking Demineralized Water,’ discusses that consumption of demineralized water (distilled, reverse osmosis, deionized, desalinated) poses several health risks that may include damage to intestinal mucosa and loss of minerals due to increased diuresis. The report states that chemically pure water (e.g., distilled, reverse osmosis, de-ionization) should be re mineralized before consumption, and that it is difficult, if not impossible, to reconstruct the complexity of the structure found in natural water. Avoiding common table salt and increasing your use of high-quality sea salt can help. The safest, most effective way to ensure you have the proper mineral levels and ratios to support healthy cellular function is with hTMA guided nutrition.
Possibly none of the commonly used ways of re-mineralization could be considered optimum since the water does not contain all of its beneficial components. Current methods of stabilization are primarily intended to decrease the corrosive effects of demineralized water. Health risks from drinking demineralized water

Demineralized water has little or no minerals. If you are using a distiller, a reverse osmosis unit (RO), or de-ionization (ion exchange resins) you are demineralizing your water. Research on heart disease and cancer has demonstrated that hard water and water that is moderately high in TDS (total dissolved solids) has a health benefit. Purifying devices remove everything from your water, not only harmful bacteria and toxic minerals, but beneficial minerals as well. This nutrient-mineral stripped water cannot sustain life even in a fish bowl. Fish require minerals, and if placed in demineralized water they perish.
Demineralized water is not considered ideal drinking water. Consumption may not provide adequate levels of beneficial nutrients. Sufficient evidence is now available to confirm the health consequences from drinking water deficient in calcium or magnesium. Drinking water should contain minimum levels of certain essential minerals. F. Kozisek
I guess it's all up to the individual... I certainly won't drink demineralized water.
