Favia losing colors

[REEDELZ]

I have a JF Sector 001 Favia and it is losing all of it colors and turning mostly red. It has just started growing really fast but over time it has slowly been losing its colors. All other lps is doing great and has good colors. I have this Favia at 140 par with moderate-low flow.

Check your phosphates. High phosphates allow brown zooalgae to grow inside the coral and turns it mostly brown/red. Just my take on it. Also 140 PAR might be a little low? Tried raising it higher in the tank?

Following. I'm having the same issues. My phosphates are almost always at 0 to close to it, (unless I've got a bad Hanna checker) but I do struggle maintaining alk. I've been correcting this with soda ash and baking soda over the last few days and hoping it'll help.
