0 nitrate and phosphate

[Baronen]

one of my torches (most expensive one obviously) and my favorite alveopora coral have started bleaching pretty bad. I feed like twice a day and do weekly water changes so I poorly assumed they were within reason but I just tested both with a salifert kit and had literally zero color change. Could this explain the bleaching? Should I begin dosing? I added some red ogo to the refugium section a couple weeks ago, this is my only method of nutrient control

Verify test results, but zero phosphate is not good.

It's not great but it's probably zero because the macro algae is soaking it all up. I'd feed more before I dosed anything.

My fiancée squirts some roe or oyster feast once or twice during the day and I come home and feed mysis etc so actually they get three feedings most days. I guess I could feed more per feeding but there’s always extra. I put a few drops of neophos in the phosphate kit and it turned dark blue so it works, not sure how else I could verify

I think so. I would
