Pink acros

You are on the blue side for lighting, a warmer k bulb will bring out reds and pinks better. Assuming your water is up to snuff, I would suggest maybe a Potassium deficiency. What salt brand do you use?
 
I have good pinks and I am using 10k xms with t5 blues, never been happier with the pinks and really all the other colors. I also think a warmer bulb would help.
 
ok i have 2 small colonies of red planet. I'm running 2x400w mh. My tank is 30in deep.
1 of them is about half way up and is light in color but the other is at the bottom and has an emerald green base and red/pink tips so the lower one has done better in color.
good luck
 
Water is perfect 7 dkh 460 ca 8.2 ph nitrate 0 phos 0.02 potassium is the only thing that runs low I have to dose that everyday because the zeo stones. I have fantastic reds pinks on everything else but acros and it's not pests I check for that stuff weekly. I'm guessing it's the light might be too much so I've moved them to the left and middle since that's where all my other stuff has great color.
