I still would rather use my own RO/DI unit. That way I know just how well the water is filtered. My water was around 110 TDS going in the unit and is at 1.5 TDS coming out. I think that is well worth the money.

My walmart has the culligan machine in the back of the store. I use 2 5 gal spring water containers and fill them up. and put the cap on so they don't spill in the car, easier then buckets. Oh, when you take the containers in the greeter puts a pink sticker on them so they know they are your containers. It costs me 3.10 for 10 gals of water. You can get the RO water in gal jugs but costs alot more, more then twice, and pain to get all those jugs in the house!

Puffer,
I was just at Wal mart this morning and I got 7 1/2 gals of RO DI (doing a partial water change today). I was wondering about the Culligan machine, if that was RO. If I bring my own containers in, the water in that machine should be fine for my tank?
Thanks a lot!

Funny, I just searched my Walmart today and no RO machine. I did buy the 58 cent gallons though. I went with the distilled after much deliberation. Sounds like I should have gone with the drinking water instead?
Can someone explain exactly what the difference is between the two waters? As in what one has that the other is lacking or vice versa?

I think someone said it has to be a Super Walmart with the grocery store to it. I checked my local Walmart (non Super) today and it didn't have it.
As far as the difference:
Distilled -- Pure water free from dissolved salts. Formerly made by distillation, now produced chemically by demineralisation.
Reverse osmosis -- also known as hyperfiltration, is the finest filtration known. This process will allow the removal of particles as small as ions from a solution. Reverse osmosis is used to purify water and remove salts and other impurities in order to improve the color, taste or properties of the fluid. It can be used to purify fluids such as ethanol and glycol, which will pass through the reverse osmosis membrane, while rejecting other ions and contaminants from passing. The most common use for reverse osmosis is in purifying water. It is used to produce water that meets the most demanding specifications that are currently in place.
Deionization -- Removal of ions. The term is generally used with respect to removal of ions from water. Deionization is commonly achieved by passing the water through successive ion exchange columns. In one column, ions are exchanged for H+ ions. In another column, anions are exchanged for OH- ions. Following a reaction of H+ with OH- ions, no ions remain in solution.

fishmamma,
the water at Wal Mart with the green labels and lids is marked drinking water. It actually has on the label that the water was ro/di processed. Still, distilled is fine too. I just wanted to let you know what to look for next time you're at the big Wal World. :yes:
