Torch corals colour Turning brown

[eqbal9947]

I dont have pics as i am on a work computer.
But my torch corals come in with nice colours. I HAD some nice yellow ones, hawt mess, reverse grail but they all just eventually turn to a garbage brown colour.
most of them are healthy and even growing heads, but colour is garbage
I run the tank at around
8.5 Dkh
1420-1450 CAL
1400 Mg
.1 Phosphate
20-30 Nitrate.
Par around the area is about 150ish.

You need more par. the nutrients look fine. Pic of the torches in question?

 

[Mr. Mojo Rising]

coral browning is often caused by insufficient light, or excess nutrients. Your nutrients look fine, so I would question the lighting.

Access potassium, iron, etc will also turn corals brown.
