Sps browning? Icp included

[VanDalsenReef]

Some of my acros have completely browned out recently. Been doing 25% waterchanges on the system from the results of my icp. Can't figure out where the heavy metals are coming from though. Used cuprisorb and will be sending out an icp in another month.
Waiting to know if anyone has an other ideas on what could be happening.

You need to check your RODI because there should not be chlorine like that. Also magnesium is high so if dosing that I would stop completely. Quite a few trace elements out of balance. Browning can be a light issue with low par or an overdose of nutrients such as aminos.

Don't think it's a light issue. Running two orpheks, 4 orphek strips and 2 kessils on a standard 90. Nutrients went up a bit. From 0.1 to 5 nitrates and 0.02 to 0.06 p04. I just changed my rodi filters so hopefully that helps. Should I send out a test sooner or just wait another month

If it's browning out due to light it's to much light. they could produce more algae causing a brown effect do you happen to know the par value and is this something that just happened, and does it possibly revolve around the lighting in any way?

Pics of the corals would help

Lighting hasn't changed and this coral is over 5 months old now. When I was able to test par a while ago it was peaking at 800 or 900+ 250-300 on my sand

This is something that has just happened

Yeah before and current pictures would help but with that description it points me at nutrients. But also it could still be light shock from 5 months ago in combination with nutrients

Where is that ICP from out of curiosity? There are reported values that seem to be far below the limits of detection. Like Holmium 0.005 ppb.

Lol this is the one I was wondering about, is uranium a normal icp test?

I thought nutrients too but my system has a hard enough time getting over 3 nitrates. And even to 0.1 phosphates. The acros have actually been coloring up before whatever happened, happened .

My main culprit

I would probably get a comparison ICP from ATI before I made any significant changes, if I were you.

Hmm I can definitely see the change but in the left picture I see it starting to brown on the tips then it looks like it works its way to the center, clicking left to right quickly I see the algae around it changing also the coral under it growing so it is strange, but I still think nutrients and lights are going on, maybe it was fine with the high light but a combination of nutrient fluctuations and the high light is making it over produce zoox, because it looks healthy and still looks great with the more brown and teal blue green. So something is going on maybe just a delayed reaction to something a while ago, hopefully more chime in on possibilities.
Either way great looking pictures!
