Finding ultra-pure water locally...

Albert, thanks for the info. This evening, I just followed your lead and ordered a four-gallon case of my own from microscopes.com.

Albert and Cincy_bob - what sort of storage container do you plan to use? From the Finding Pure Water thread, I read amber colored glass jugs should work better than plastic.

I'm keeping my Reagent grade water in whatever kind of gallon jugs they ship in.

I have an IKEA roll around that was supposed to be for a kitchen that I use for my RC machine. I keep all the cleaners in the drawers below the work surface.

Guess I could refill the 64 ounce container supplied with my Walker Prelude kit as it empties. That's a handier and more manageable size container than the gallons.

I have a 180 gallon saltwater aquarium with a 55g sump and had to purchase an RO/DI unit due to well water. They are not expensive. I think mine was less than $150 for a 75 gallon-per-day. I need to add nearly 2 gallons a day due to evaporation and I do a 35 gallon water change monthly. Remember, it takes about 4 gallons to make 1 gallon of filtered water. I have the "waste water" going to my washing machine. Do not store in any ole plastic jug. Glass or a #6 plastic container will not leech. Not a bad idea to own a unit for drinking and getting out all of that garbage that they treat with. You should only drink "RO" and not "RO/DI". Most units have simple valves for using either/both. That will be the day that I pay(get ripped-off) for water!

Jtimothya, maybe it's naive on my part, but I figured that whatever sort of storage container the Reagent water has been stored in to date will be fine for continued storage at home. So that's what I am planning on doing unless I find it's a bad idea...
