ICP test results need help

[Jr'sReef]

So as title reads, I received my test results and not sure what appropriate steps I should take.
I noticed something off when my birds nest started bleaching. Then started noticing the coraline algae getting white patches. So before sending the test results I did 100 gallon water change to quickly try and dilute the issue. (Then took samples of the aquarium) and then While I waited for the results I did another 50 gallons. 50 total after icp test so far.

My tank is about 450gallons Total volume. Mixed reef mostly consists of soft corals.
What I’ve done after receiving the results. Cleaned the sump, the skimmer, filter socks, fed less, added a bag of phosguard & cleaned/added new GAC to my reactor.

Should I start GFO? Last time I ran it in a reactor years ago i bleached a lot of corals. I want to hear your opinions and what you would do. Any help is appreciated

Here are the results.

1. how long has your tank been running?
2. how long have you had elevated phosphate?
If you have had very elevated phosphate for a long enough time, your sand and rock may have absorbed a large amount of phosphate from the water column. As you lower your phosphate in the water column with water changes or whatever the phosphate can leach back into the water over time and maintain more elevated phosphate levels than would be expected based on what phosphate you are adding through feedings and such.
Do you have an algae scrubber or big refugium set up? Removing those nutrients long term might be most cost effective and safest using a good algae scrubber.
If you wanted to more aggressively attack the issue you could remove your sand bed in thirds or so and replace with new sand. Pulling out the rock and removing the sand bed under it in thirds will allow you to prevent a large amount of phosphate in the sand and detritus from entering the water column over time. If you aren't attached to a sand bed you don't necessarily have to replace it.

Hmm that’s good info. It’s been running a little over a year. Never really checked phosphate just always checked the usual PH, salinity, calc alk and mg.
I have no algae scrubber currently set up nor a true refugium. Although I did want to set up a 30 gallon separate cryptic zone filled with LR plumbed into the tank just for pod population and sponges etc. but maybe that should take a back seat for now.

I have a total of 24 fish, all of them on the small side except a mata tang who is the biggest at 4” so he’s still small too.

I actually don’t like the look of BB so maybe have to do more work on my sand.

Other than Calcium and zinc....test looks pretty dog gone good.
For PO4, you can use a phosphate resin in your filter flow or Red Sea Po4, No3 to reduce gradually. Water changes will help as long as your water is free or low on phosphate

May want to focus on why there is so many metals that are in the yellow (copper, barium, zinc). This suggests you have some metal 'somewhere' in your system - and if its not causing a problem yet - it will be.... I mean your copper is 3.49 it should be 0. Your barium is 6 x over the limit.

Ok will look into it. I do know I dropped a female connector into the tank and couldn’t find it like a year ago. I was wiring something and dropped it in. Maybe that can be the culprit?

That would do it. You definitely have some metal issues and a PO4 issue.
