Each tank is going to run different. He’s having amazing success running .25 but let’s say I ran .25 and could have completely different results.

But back to the OP let’s see some pictures to help ID what’s going on.

Mines roughly around .25-.28

Those don’t look bleached. They look like tissue necrosis. Probably starved from not enough light. I have a single prime 16 over a 6 gallon frag tank and I was shocked at how low the par is.

The answer is no. 0.30 po4 is not extremely high and it will not cause rapid death to frags. 0.03 is more likely to cause harm to frags than 0.30.

What’s lights do you have and how about flow? Did this happen over night or was it gradual? How old is this system as well? Also can you try and take come pictures with the whites on instead of blues.
