ICP question

saturn13 · Jan 10, 2021

So I've been having some issues with random coral die off , chalices don't seem to like my water and certain zoas, usually the skirts seem to be pulled in or they close up completly and die off, a couple pics, the closed are LSOH, and the other pink diamomd. and my elegance not opening either. Numbers have been steady. Water changes about every two weeks. Does anyone think ICP test will show me anything that will help? And which brand is good?

temp 77.0
salinity 1.025, 33ppt
calcium 443 ppm up
alkalinity 9.3
phos 0.05
nitrate 10ppm
ph 8.3 good

Thanks,
Dan

It's possible you have something like heavy metals in the water that's causing the problem. That would be shown in an ICP. Personally I find ICP tests to be helpful.

I've had good success with Triton and ATI. Triton is probably the fastest in the US now that they have a lab here. If speed is a priority go that route, but otherwise I'd suggest going with ATI because it also includes a free RO/DI ICP test which is a nice bonus.

Ok thanks, hopefully nothing too bad, my tds is 0 on output on my rodi, but im sure that is limited to what it identifies.
