RODI results

 

[deaclauderdale]

My first ICP test but things appear to look good to me. Would appreciate any insights the forum might have.

That’s crazy low on salt. How are you measuring it

That was exactly what I was going to ask .

Yeah looks like your SG is around 1.021 or so.

Why do you all say it's low. Looks like the ICP says 35ppt which is what I measured it using a refractometer that I calibrate weekly.

Would that kill some of my corals if the SG was low? Anything else stick out to you all?

 

[mattyzang]

for the RODI results, your salinity is 30.81 PSU?

You’re looking at the standard reference. Those are recommended levels.
Your level results are the first column. You have your tank and rodi posted backwards. That’s why you tank value all has undetectable on the first column. That’s good for your rodi though!

you have a few low trace elements as well as some that don’t normally register for me. Vanadium I have to dose, usually undetectable. Copper normally doesn’t register but did for me recently during issues. Same with Tin but yours is much lower than mine was.

bromine and iodide are pretty low too. That is something that is normally depleted in my tank and I have to dose. I wonder if neomarine is just lacking in those elements?

Once I get home I’ll look back in my 180g results. I kept getting stn overnight and could not find the culprit for everything testable at home. That’s around when I started the reef monnshiner program and started to have success again after making corrections. Looking at your test I feel like the low flouride, iodide and bromine were contributing factors.

Andre had a free RM handbook. Even if you don’t want to use the program it breaks down your ATI ICP test pretty well. gives recommended values and tolerances and some descriptions of trace elements. It also has a helpful troubleshooting guide. He also has a Facebook group that is extremely helpful for troubleshooting and a bunch of experienced eyes that ATI ICP test religiously.

Just got home at 5:30 calibrated the bulk reef supply portable refracto (was at 32 when solution applied) to 35ppt. Tested tank water and it shows 35ppt.

I want to trust the ATI results and believe that I should but I don’t have another Salinity tester and I don’t want to try and raise my salinity using what could be a faulty refracto.

Here’s what ATI recommended to bring things back in line.

Find a couple of ppl and I mean a couple (at least) to verify salinity results.

Working on that and I ordered a salinity pen just to be safe. Gonna try and find a store close to me tomorrow so they can test salinity for as well.

Which one, the ice cap is very unreliable

 

[joseserrano]

These are very accurate, but a little challenging for me to read. Also need a graduated cylinder (cheap on Amazon)

Hanna pinpoint but I will also pick up one of the hydrometer's as well. No such thing as having to many useful tools.

I got a hanna checker and a milwaukee bro if you wanna use it

 

[Smite]

I've found my hanna checker to be very reliable. I really like that they worked temp into the pen as well. I calibrated my apex and water mixing station's heater to it so they match perfectly. Great tool but I know some struggle with it for some reason. I just calibrate often, rinse in RODI after use and dry.

Would you mind if I stopped by and had you test my water for me?
