Ati test results

ontop27 · Feb 5, 2018

If you only saw this report and assumed everything else was in check..could you point to an lps issue? Acans, went from amazing to slow deaths, 2 scolys down, blastos okay, lost a bunch of frogspawn and hammers. This has been going on for about 6 months. Everything else fine, no pests, no nippy fish, no swings of anything. Metals seem high (new rodi filters) and iodine seems low. What would you go after first? Thanks for your help!!

Rodi

The tank has elevated copper and zinc and that might be an issue. Not certain what levels are a problem because it is not as easy as looking at a number. My tank had about that level of copper at one point in the past without an issue, but your levels seem much higher in copper than we normally see.

You'r RO/DI looks to not be 0 ppm TDS (pretty high, actually), and it has copper in it. That could be the source (but it is a reasonably small source). I'd replace the DI now.

That said, I'd also look carefully for other metal parts in contact with the water.

The tank salinity is low and I'd raise it. That will boost somethings that are low, such as potassium.

Is there a time frame for the membrane to be effective? I had literally replaced it like a day prior. I forget my exact number but my incoming tds is under 100 and outgoing is always zero. Generally i replace the other items when i see most of my di is used up (color changing) so i rarely see any tds outgoing

Maybe ill run some cuprisorb in my reactor. Ive tried those pads before and never noticed a color change

It is the DI that is the issue, not the membrane. Not sure what happened, but the number they show indicates tens of ppm TDS.
