TDS reading of 11

[aus1230]

Just installed a 5 stage RODI system from bulk reef supply. They initially sent me a system that had leaks and I was able to get 0 TDS from the meter. After installing this one I am unable to get 0. I’m sure there’s a possibility that this meter could be wrong? Currently getting 10 TDS and really need some water at this point.

I do know that the TDS meter 'pins' need to be oriented in the proper direction inside the connector. I'll see if I still have a photo-- but it came from a BSR video. However if they assembled it, you would think it came to you configured properly. Sorry this is happening to you.

Would you feel comfortable using this water since I am unable to get some RODI water from my LFS today and my rear chamber is low.

Are you getting 10PPM TDS before, or after the DI stages?

I believe it’s 10 after I only know that the meter is on the “last stage” before the water outlet.

Is the meter before, or after the last stage?

— just follow the electrical wires to see if they go into a plumbing T fitting which is on the tubing you draw water from, or if they go back behind the RODI system somewhere!

When starting a new RODI, you may need to run it for several hours the first time.

At 10ppm, we don’t know where the issue is, it could be bad membrane, which would exhaust your DI super quick, or incorrect DI, or exhausted DI, all might lead to a 10ppm reading.

You need to check the TDS, right after membrane. If it has not reduced source water by at least 95% of the original source water, than that is gone.

If it is working, your (say 100ppm for example) incoming will be say 5ppm. That’s working.

Then move to the last stage, DI. If your not getting 0 after this stage, it can be.

-has not run long enough after newly set up.
-is incorrect type, you need mixed bed both positive and negative.
-is dried out or simply exhausted.
-water is not following through the media.

Maybe those things you can check.

Me, I don’t use water above 2ppm.

I don’t know what the 10ppm is made up of.

You kinda got to know that for sure.

I’m guessing it’s before?

For the time being I guess I’ll allow it to run for another hour just to see if that helps at all. I went ahead and ordered a TDS meter stick. Which shows 7ppm while the one on the unit showed 11pm today.

Disregard. After a quick world wide coral video I realized that my last stage filter was probably not positioned correctly when sent from bulk reef supply after a quick reset I am now receiving 0ppm

Great ending!
Thanks for the update.
