ATI test shows copper and phopshates in RO water?

[bozo]

This is so weird

All my other ATI test show no copper and phosphates.

I have zero TDS after the DI.

What should I be changing to fix this?

Thanks

Bump

If your tanks saltwater is showing 0 copper and your corals look fine, maybe there was an error. If your tank shows copper then run some Cuprisorb.

Do they test for other ions in the ro/di as well? If so, can you post it?

Thats some fantastic logic. My main tank analysis does not have copper! Thank you!

Yes they do!

Just posted below.

Thank you

What about major elements such as sodium, calcium, chloride?

I guess ATI doesnt test for those in RO water. Should I go with a different ICP test provider?

It does test for those elements for the tank water though.

Here are the latest results for my tank water. Total tank volume is 50 gallons.

I sent a sample of tank water right after my BRS 1.1 mL per hour dumped an entire bottle of ATI Essentials Pro Part 2 (calcium and magnesium) into the tank.

I've since then rectified that issue with a 100% water change.

I've also dosed PO4 (via Na3PO4) and NO3 (NaNO3) to 0.1 PPM and 10 PPM respectively.

I have some work to do with my water chemistry forsure.

Given the tank values, I would not worry about the ro/di values.

I wouldn't trust ATI RO water analysis. I sent two tank samples in with RO included. The RO samples were taken from the same container at the same time yet ATI sent totally different results for the samples of RO even tho they were the same water. I won't bother with ICP again unless something really mysterious is happening in a tank.

Aren't ATI and Oceanmo the benchmark compared to others available?

Thanks Randy.

What are your opinions on these major elements im lacking apparently.

Do people actually dose these elements?

Pretty incredible

That’s what I thought as well which is why I’ve been using ATI

The salinity is high, the alk is a bit low, and you might consider a trace element supplement such as Tropic Marin A and K.
