I just started filling up the container today. Its a 35 gallon brute container. I read on another board that anything less than 10 ppm is acceptable for a reef tank. I may have to store this water until Monday before I start the tank though Saturday would be the earliest. I'm waiting on a live rock shipment.

Was it a new container or has it been used for other stuff?

Brand new. I picked it at at Home Depot and gave it a rinse and wipe down. The water has been sitting in it for a couple hours now just being heated and circulated. I just tested it and got a reading of 0. I'm going to check it out again before I go to bed. I guess worst case scenario right now is my ppm is in between 0 and 1. No too bad right?

I think you will be ok!

I'm sure you've heard of the wives-tale about that you're not suppose to drink DI water, right? Well like any good myth, there is always some truth to it. Water with a TDS of 0ppm, is about as 'pure' water as you can get. Water that basic, is pretty unstable, and likes to bond with stuff, even to the extent of pulling humidity out of the air, and any particles with it. This is where the wives-tale about drinking water stems from. If you drink DI it will rob your body of some nutrients. However you would have to drink sooo much of it, you will likely feel the affects of water poisoning first.
In your case, the DI water is likely pulling from the brand new Brute. With the container being new, it's important to monitor phosphates. If anything is going to leech out of a new plastic container, it will be phosphates.

That is going to strictly depend on where you're getting that water from. 10ppm from right after the RO membrane is fine. I guess someone could say tap water with a TDS of 10ppm is fine too, but I doubt that exists. But if you have an RO/DI unit, 10ppm is absolutely unacceptable.
It is theoretically impossible for water to pass through DI media and not have 0ppm. Once the DI media is exhausted, it will start leeching the compounds it's absorbed. Not good. I usually wait till I'm getting 2ppm out of my DI, and then order new media.
Side question, what TDS meter are you using?

Agree.....Is this the reading your getting before adding salt? Are you using the same meter or 2 different meters? I'm assuming your testing your container with a handheld unit, and your RO/DI has an inline....Are you sure both meters are calibrated?

I only have the handheld meter and this is testing before I have added salt.

i just had a ro unit installed by culligan and the guy that put it in for me said that my tap water tds is about 115, and that after the ro filters it out it would be 10-15 at the lowest
115 TDS isn't bad....considering what some people have....Your TDS can vary during the course of the year as well. I find it hard to believe that he said a TDS 10-15 is the lowest....What is the rejection rate of the membrane they are using in the unit?

Are you sure the meter is calibrated correctly? It's possible it could be off?????
