Where can you purchase RO water if you don't have an RO unit. Is it the same as the bottle water that you purchase at the places that sell filtered water for water coolers??

You can find the bottled water at alot of stores. Make sure it is RO water and not spring water. Aquafina is RO water for example. I will tell you that in the long run you will be spending alot more time and money getting your water from the store.

Now RO is standing for Reverse Osmosis is it not so I can make sure I am looking at the right stuff.

Dominon had 5G Culligan machines for $2.99 a fill.

A great way to insure it's R.O. is by testing the Gh and Ph of the water. If it's true RO it will have niether. Some places who sell water do not always change their membranes when they should.

Im a bit confused by this post

GH stands for gallons per hour
Ph Stands for alkalinity acidity value

RO water will be aggressive as it is very low in TDS, therefore it is acidic
But it will have a value.

Maybe I misunderstood....Please elaborate

If you search for a water supplier in your area you should be able to buy a package and get it for about $2 a 5 gallon bottle

Gph: Gallons per hour, Gh: General hardness popular test in freshwater Aquariums. RO is also widely used by people caring and breeding discus. If the Gh(general hardness) is to high in the water discus eggs become too hard and can't be fertilized, so anybody caring to breed discus has to be aware of this. So this test is also important to check the integrity of the RO unit and it's water. It's a easy test just to make sure the water you are using is good. This is not a freshwater forum, but I do the same test's before my water goes into my reef tanks. And your right there is no such thing as no Ph, but the reading for Ph should be extremly low.

Even if you're buying water from a store - it's a good idea to either purchase or borrow a friends TDS meter to ensure that the store is replacing the filters in a timely fashion - resulting in low TDS water.

I have seen (and heard of) stores not changing out the filters often - and the purchased water having very high levels of TDS.

It's always better to be safe then sorry - especially in this hobby.
