favi and chalice coral help

[andrew5013]

So it seems that my favia and chalice coral are starting to lose their color. Any suggestions on where they should be placed in the tank? I have a 12 gal Nanocube with 3.6 led retro kit from nanocustoms. As of now they are both in the lower level of the tank. Thanks

I would lower your photo period if you didnt acclimate them to the light they may be bleaching.

Some info would help! Temp, how long you've had them, changes? Salinity? Cal? Alk? RODI?

i would say the light change is a likely culprit if water chem is constant
