Plate coral suddenly started bleaching on two sides

[tw5090]

Hi all! I’m looking for some help! My plate coral recently started bleaching on two sides. I cannot figure out what is causing it. I attached my parameters and a picture of the coral when I dipped it tonight. I cannot find any info on what infection looks like, how to treat if so. My salinity is stable, usually almost every week I check the salinity is as .25 but more often then none it’s at .30 Help!!!!

Phosphates look very high compared to your nitrates.

I don't know if you dose anything but I does Red Sea AB and C Foundation and noticed that it slowly raises my salinity. Occasionally I will remove a gallon of salt water and let ATO mix in a gallon of fresh to lower .

Phos is high. Should shot for about 0.1 but not sure that it would do that to a plate coral. Stability is the most important thing.

I have always kept my phos that high, it’s part per billion on that particular test I use. The tank is a year old. Yes, I dose call parts. Alk, phos, nitrate, and cal. All separate.

Mag is supposed to be 1350 or was 135 your test result ?
I’d try getting nitrates up a little .
if your salinity is jumping from 1.025 to 1.030 or was that in ppt ?
25ppt to 30ppt ?

the 2 major parameters that corals do not appreciate fluctuations are salinity and alkalinity .
Corals can live unhappy with nutrient levels fluctuating

Last weekend when I did my water change and testing alk was still at 1350, and salinity was at .030 now currently at .025

I think I’m reading your test results incorrectly .
Magnesium numbers are more likely to be 1350 , not alkalinity .
And for salinity specific gravity ( SG) 1.026 is nsw levels .
0.25 I can only assume you mean 1.025-1.030 ?

Yes you’re correct! I may have put it in my phone like that not noticing. I log everything in my computer afterwards!!! I double checked!
