Lfs busted...

On a whim I decided to test the TDS level on the RO water I recently bought from my "trusted" lfs. I was floored when it read 482 ppm!!! I thought perhaps my meter was malfunctioning, however when I tested my well water it was in the typical range it has been, which averages 64. When I tested some distilled water I had bought in a gallon jug from the grocery store it read 0ppm. I had some "RO" water left over in another container that I had purchased from the same lfs a week earlier and it read 84ppm. So it appears that my lfs owner is obviously ripping me off, but any reason for such a fluctuation? 482ppm one week and 84ppm the next??
Also, I typically do not use prime on RO water when I do water changes. If this was actually city water, wouldn't the chlorine and other additives affect my corals and fish? I don't see any issues today.
Not only am I furious, I'm confused. I have every intention on confronting this person.
At least now I know the main source of my algae issue. I wonder how often this goes on.

There is a chance it's residual salt if they use the same bucket for mixing their salt water and for storing RO water.

For example, my RO/DI bucket always reads out to 0 tds if everything is clean. A while back I threw my water changing pump into the resevoir bucket so I could pump the water up to my mixing container. Even tho the pump had been rinsed there was a tiny bit of residual salt on it. That alone brought my tds up to over 10. And that is from just a rinsed pump. I did the math, and it does make sense seeing as how our target salinity is about 34,000 ppm.

That bring said, even if that is the cause, there is no excuse for such poor husbandry in what should be almost pure water.

I'm truly hoping the cause for the ridiculously high reading is something like that rather that blatant dishonesty. And you're right, even if it's inadvertent, it's still unacceptable. So disappointing too.
Thanks for the reply.

See if they will put some in something that you know is clean (a glass from home?) and test that.

I've had the residual salt thing happen to me before with my own RO setup. It's usually around 3 ppm and one day it was in the hundreds in one container, but at 3 in the others. Of course the high one was the first one I checked.

That was my plan. I'm going tomorrow. Again, I'm really hoping it's residual salt. I love this particular shop. Great prices, healthy corals and fish, and the so far the owner has been straight up with me from what I can tell.
My only other option would be a big box chain store.

You could also invest in a ro/di unit for yourself.

I caught my lfs selling me water that had nitrates in it, that was my calling to get my own unit. Sometimes they just dont change their filters enough, whether on purpose or accidentally, you need to get what you are paying for in my opinion.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.

Haha I know I know. I've been putting it off because I only have a 20L and I'm usually at the shop every week anyway. But you are exactly right. I'd save myself a headache and some money when it's all said and done.

I thought I'd run this by folks on here. I did talk to that particular owner about the high TDS reading and they agreed that it was likely residual salt. Then this person explained to me that I was buying RO water instead of RODI. I was then told that the reason being is that ideally you don't want absolutely everything removed from the water. I'm skeptical now. Any feedback/opinions welcome.

You definitely want RO/DI. It will remove everything and then your salt mix will put back in what you actually need (buffers, trace elements, etc..) for your reef.

That's what I've always thought...
