okay so I am somewhat new in the spa world. i have a few acros and some montipora, the montipora look great but the acros are not extending their polyps and some closer to the light are turning a lighter brownish color. no nitrates no phosphates, what could this be? i run aqua illumination sol whites at around 50% and i have two mp40s for flow...

the frags have been in the tank for 4 months, they just don't have the color or polyp extension of when i bought them. i will work on getting pictures up, my alk is 2.6 ca is 480 and mg is 1340

"Subdued colors and dark or brown tissue is, in most cases, the result of high nutrients. It can be assumed that either nitrate (NO3) or phosphate (PO4) is present or too many other elements are available."

 

Do a water change and stop feeding so much.
