Frogspawn and now Hammer bleaching

[fjuriolli]

Hey guys, couple days ago I posted this https://www.reef2reef.com/threads/first-lps-coral-losing-colors-or-is-he-okay.664741/#post-6722467

My frogspawn was bleaching due to 2 factors: LED light was too close from water surface (only 8cm) and too much light (it was running at 60% at peak 14PM to 19PM, 60% blue and 30% white)

At the meantime, I got a sweet deal for a hammer colony and he also started to lose color.

OBS: the lights are about 160W and I have a 50 gallons reef give or take.

My parameters are pretty much the same:

KH: 8.8
Ca: 420
Mg: 1325
Salinity: 1025
Temp: 26.9 constant (chiller)
Ammonia: 0
Nitrite: 0
Nitrate: 10
Phosphate: Unknown (I dont have the test yet)

What I did?
- LED light is now 25cm above water surface
- LED light running at 40% (at peak 14 PM - 19 PM blue leds are 40% and white leds 10%) - I will slowly increase after the corals get better

First, a picture of my frog taken today (looks like he is recovering):

No two photos of my hammer taken today, first one is with lights off

What you guys think?
Should I wait or I need to do something?

Changes in coloration secondary to lighting issues happen quickly. It may take weeks for a coral to show a positive/favorable response to decreased intensity. I would proceed slowly and not increase the intensity.
