Large water change after using high TDS water?

[mikebusc]

So I just realized, unfortunately, that my RO water had a high TDS reading. I’m reading like high 40s low 50s right now. It’s probably been like that for the last few water changes and months. Should’ve realized when I had a couple bad outbreaks of GHA. Obviously, I was really lapse on changing my filters. I’m going to put all new ones in, it’s a four stage, tomorrow. But as far as the water already in my tank, should I do a couple of large water changes because of the high TDS? Or does it not matter at this point and just start using the new water?

I would not do anything about it. I’d just move forward as if it didn’t happen. :)

What he said. Only thing you can do anyway. It'll be fine. What you introduced will leave in good time. And what doesn't is at such low concentration that it'll be inconsequential.

Will do! Thanks. I’m going to be more aware of my readings from now on. How often do reefers usually test for TDS? Weekly? Monthly?

In their ro/dI? I'd take a reading each time you use it. You need to know when the di depletes.

Get yourself an in line TDS meter. Just push the button every time you make water.

Ok. I’ll look into that. Didn’t realize such a thing existed.

For a four stage RODI, you'll want to know TDS in three locations (tap, RO, DI). See the three probe TRM1 here: https://www.buckeyehydro.com/in-line-1/
