Copper in display advice needed

[nightmarepl]

Hey guys so I’ve been noticing a lot of my corals specially my hammers have been looking pretty bad tested water everything looks good decided I’ll see my rodi saw my resin got depleted sooner then usual as reading 18 ….
Changed the resin reading 0 now but i thought I’d test for copper and found out i have 0.21 copper level in the main display
How bad do you guys think this is how much is it effecting my system i got cuprisorb and carbon coming in tomorrow I’ll hit it with both

Not a reliable reading for copper high range. To confirm you have copper in the display you need to run an IcP test.

put Poly filter, it will absorb/remove copper, i use this filter pad (Seapora 4041 Filter Floss Aquarium Filter Pad) few times in my Rubbermaid tub.

With a tds of 18 on your rodi you could potentially have other high trace besides copper in toxic levels such as zinc, tin, iron etc. Get metasorb and run asap. It’s the most effective. If you really want to know the levels you will need an MS ICP test. You really need to pay close attention to the color change of the DI resin, because even if it read zero, it can still let metals through. The metasorb will pull
You out of of a toxic range of heavy metals in 3 days.
