TDS issues

[Bthomas]

So on a whim today i decided to check the tds in my brute rodi holding container and found it to be around 14.. not good.
Checked the water coming straight from the rodi unit itself and it's still reading 0..
So then i got thinking about my ato reservoir since the water in there comes from my rodi brute a found it to be 755 tds!
I'm kinda in a panic now.. I'm not sure what this means or what i need to do about it..

I lost a cleaner shrimp in my tank a few days ago and couldn't figure out why, now I'm wondering if this could have something to do with it

Time to give the brute and ato reservoir a soak in vinegar.

When u say a soak in vinegar what does that mean exactly? Would wiping them down with a vinegar soaked rag work?

I would fill the brute up with as much vinegar as you can. 5 gallons or so. Throw in the ato reservoir and protein skimmer and pumps and powerheads and anything else that needs a good cleaning (take advantage of the vinegar while you got it). Then fill the rest up with water and clean all of it.

The tank and all equipment is brand new only been running since january. Nothing else should need cleaning. i think the problem may be that I just didn't clean the brute/ato reservoir with vinegar before using

I'm not sure there's anything wrong with the RO/DI storage or the ATO reservoir.

As atmospheric CO2 dissolves in deionoized water, it forms carbonic acid and the TDS will increase, even if it came out as 0 ppm TDS. If you're measuring zero after your DI resin and you keep your RO/DI storage container clean and sealed, then the TDS you're measuring is likely nothing to worry about.

The ATO reservoir will likely have much higher TDS because it's much closer to the tank and is much more likely to get dust or salt in it.

If anything, I would dump the ATO reservoir, rinse it with freshwater, and refill. I would personally not do anything to the RO/DI storage container unless you don't keep it sealed very well, or there has been some sort of known contamination event (dust fell in, a bit of salt made its way in, etc).

Well i just rinsed both containers with a bit vinegar water so hopefully that is all thats needed.
I do not however keep my rodi container sealed well. I have the tube going over the top into the container so the lid just sits on top of it.
Do you think that is a problem?

Also since i rinsed my containers with vinegar how long do i need to wait before reusing them? Do they need to air out for a period of time?

I would plumb the rodi container so it is well sealed. More than likely dust, particles and CO2 are getting into your water.

I drilled a small hole in the top of mine so I could snap the lid on

Usually after a soak in vinegar I just do a freshwater rins and let air dry or towel

Sounds good. Thanks

So after rinsing both containers out with vinegar the water in the brute is now reading 1 tds but my ato container is still at 750..
Think it's nothing to worry about?

But also not likely a problem. Just probably some salty dust getting into it. I would not worry or bother measuring it.
