Copper in RODI

[lynn.reef.nerd]

I'm currently on Well Water and the latest ATI test of my rodi is showing some copper.

Is this level safe or is there something I should do to remove this before addition to tank.

Thank you.

RODI should remove copper. I recently had a new well drilled and my DI resin got obliterated quick. I would check your resin to see if it is exhausted. I had to add 2 additional DI canisters for a total of 3. I never tested for copper, just had an elevated TDS

I also had bad luck with copper back in the day. Cuprisorb wouldn’t hurt to run. I’m not smart enough to interpret that lab value tho. I just wouldn’t want to see it in my ICP

It deplete my anion like crazy but I'll do a new swap and maybe add a couple more di resin.

You’ve got a rad operation going on with that fish shed! Love it

Can you post the rest of the analysis?

Burn it all to the ground and start over! And give me the corals first!

That must be after RO/DI? Doesn't look like raw well water.

Yes, after 7 stage.

Yes, after 7 stage.

Was it 0 ppm TDS after it?

How many DI stages?

I can check the TDS again when I get home. If I remember correctly, around 0-2 but not certain as of right now.

3 DI (1 mix, 1 anion, 1 cation)

I'd try to keep it at zero with the potential for copper. Flushing any copper pipes before starting the DI may also help, if it is dissolving copper from your pipes.

Is the current concentration of copper a cause for concern?

I would send for a different test before you do much other than maintain your RODI.

That’s a hard to answer question since it may accumulate.

Hi Lynn I have a question about torches. I consider you an expert so hopefully you can field this question. Every time i look into a torch thats supposedly yellow it turns out to he green. Same with hammers. Any advice as to how I can find one that is really yellow? Thanks in advance.
