Needing 100 gallons of RO / DI by tomorrow in Cedar Rapids

I'd use tap for a leak test. If ok, drain and then fill with ro.

 

Yeah, definitely just use Tap if you're only leak testing. I just filled up my used 120g RR w/ RO/DI and wish I had used tap to begin with. Even though it looked like I had the tank cleaned spotless, there was a bunch of crud/sand still in between the narrow overflow walls that I hadn't realized. I contemplated dumping it all out again and starting over.

Do you already have an RO/DI and just don't have enough made up yet? With that size of tank, you are going to need your own RO/DI filter rather than having to lug water jugs around every other week.

 

If you really think you need it, I could start making some to have ready for tomorrow, but not sure how you would transport that much water though?

 

I have 30 gallons made up right now. How do you plan on transporting?

 

I have between 15 and 20.

 

I agree with tap water for test. Jus throw a hose in it and fill it up for test. If its all good drain it and use towels or shopvac to drain it all out. Wait til tomorrow when its bone dry and move everything over with your existing water. Doing 100% wchange your gonna have a algae outbreak and possibly deadloss i would think. Id use as much old water as possible and fill the rest with fresh.

 

when i did an initial fill on my 120 gallon tank i went to culligan and purchased a type of water from them that was more stripped and even better then ro/di water. i remember it having a red cap on the five gallon bottles. i had approximately 80 gallons of ro/di made at my house but needed extra to get up to the full tank/sump volume. i rememebr it being roughly between $7-9 per five gallons plus bottle deposit but you get the deposit back upon return of the bottles...for me that wasnt a bad price...not sure what price range youre wanting. i also didnt need all 120 gallons either. also it probably wont be much help to you as you want to do this on a sunday and culligan wont be open until Monday. not even sure if there is a culligan near or in cedar rapids but thats what worked for me when i was in a bind.
