ATI ICP Results; I'm confused

[Chaos reef]

You have high copper in your tank. Honestly you do have several things that should be done, but try to not do to much at once or go to fast. But copper kills corals and inverts when elevated. Several other good ideas by everyone, but I've lost several corals to less copper than you're showing on your icp

Yes, I agree the copper is high too. I'm not certain if its high enough to be an issue (icp doesn't say what the chemical form is).

Something like a polyfilter or metasorb might be useful.

Yeah, the copper showing up confused me. I do not use it!

Yeah, I'm confused by that one too, because I do not use copper! I'll try the metasorb. Thank you for the suggestion.

Yes, sodium silicate. Dinos have been verified by microscope. I'm dealing with LCA.

"Fertilizing" diatoms with sodium silicate will drive nutrient concentrations down. It may cause problems in corals, maybe due to this nutrient consuming effect.

Oh, sorry, I have overlooked copper. The combination of zinc and copper in about this ratio may point to brass somewhere in your installation, most likely a valve after your reverse osmosis. Can this be?

True, in a dino situation it is desirable to keep N and P and Si up.

The ICP results from my rodi sample showed no levels of anything. I take the water directly from the rodi and put it in a plastic bucket to mix up my salt solution. I cannot think of anything that has brass in it. Everything I use is plastic with the exception of pumps (impeller shafts are metal) and heaters. I have racked my brain trying to figure out what had caused this mess.

Standard pumps that other reefers use?

Interesting. I didn't know this would cause nutrients to drop. I've read that phosphate readings will be off, but that's all I've seen about adding the sodium silicate. I do have NeoNitro and NeoPhos on hand if needed. I test weekly with Hanna.

Interesting. I didn't know this would cause nutrients to drop. I've read that phosphate readings will be off, but that's all I've seen about adding the sodium applicate. I do have NeoNitro and NeoPhos on hand if needed. I test weekly with Hanna.

The tests won't be off by much, typically. They would read a bit high.
