Hammer/frogspawn problem

[pedro2003]

Hi. I have a problem with a coral that i believe it's a mix of a Hammer and a Frogspawn. It opens a little less than before and seems like it turned transparent. When i bought it, it had a beautiful dark green color tone and remained like that for a few days. Now it is transparent and with a very weak green. My other corals seems to be doing fine. This hammer/frog sits in the middle/higher part of the tank. I don't have a par meter but the lighting doesn't seems very strong.



DIY LED 45W lighting (main) (Programmable)

2X DIY LED lighting ( weaker and bluer for sunrise and sunset effect) (Programmable)


Alk ~ 8,5
Magnesium ~ 1450
Calcium ~ 450
Ph ~ 8
Salinity ~ 1.025
Nitrate - 2 ~ 3 ppm
Phosphate - (my currently test seems to be low quality, but i know it is below 0.1 ppm but not zero)

The others appear to be softies, and they usually do well even in early systems.

How old is your system?

LPS are a bit more demanding then the softy group.

The system is a bit more than 1 year old. Most are softies, but as you can see in the picture, i have a goniopora (LPS) which seems to be the healthiest coral in my system...

It’s bleached due to insufficient lighting, your zoas also look like they are stretching for more light

I thought about that too. But what will explain that goniopora at the bottom level of the tank?

Also, only this zoas was taken over by algae. I am trying to remove.
