Help!! Corals STNing

[bonomo53]

Went through something similar last month with some of my sps stn while others were perfectly fine showing great PE. It looked like alk burn but my alk was steady in the 7s. I ended up doing 20% water changes for a few weeks changing carbon and dosing a small amount of iodine each week and that seemed to stop the stn. I'm still not sure what it was but i have some crazy ideas like the possibility of pollen or insecticide since i had the windows in the spring.

Help!! Corals STNing

I got my Triton test back today.

It shows no heavy metals except Aluminum, but still green.

As for Macro-Elements, it's a bit all over he place. I'm not surprised by Calcium, as I've been just about 400-405 on my test kits. Mag is a surprise as my test have been 1420-1440 on both my kits which are brand new. I've never tested The other ones. Would the low potassium or Sr really affect corals that much? Boron is an interesting one as I was having a discussion this past week with one of the workers at country critters and he said that low Boron could lead to pH swings, but it doesn't look that low.

Iodine looks extremely low and I'm surprised it's not red, so I'll need to pick something up.

Lastly, my PO4 looks good. It's annoying that my Hanna checker always shows zero! I have the Phosphorus checker but it swing so much from test to test. I've been getting between 2ppb and 11ppb for the last week or so.

So what does everyone think? My parities are starting to look a little better, but everything else doesn't yet.

Here's the link to whole test.

When was the last time you calibrated the PH probe? Do you have two PH probes?
Usually when everything looks perfect it MAG. Some of those test kits are tricky to get an accurate reading. Have you double checked the TDS in your topoff water?
What's the bio load on this tank?

If a few quick water changes help, its not voltage leak.

Thanks!! I'll try to calibrate my probe. It's been a while.
I check the TDS every time I make water and its 0. The MAG is confusing as both my kits still say 1400+.
As for BiOload,
3 Anthias
2 clown fish
1 hippo tang
1 Tomi Tang
1 falco hawk fish
1 leopard wrasse

But I Have to constantly dose nitrate and once or twice a week PO4. Otherwise they will drop to zero.

I haven't dosed any carbon in several more months.
