Hello everyone!
I wish you a great start to the week!
I noticed about 4 weeks ago that my pavona is starting to slowly turn a bit brown, as shown in this picture.
Its starting on the inside, the outside still green.
The coral is in my tank for about 5 months now. It was placed lower in the tank before, i moved it higher up when i noticed the brown, thinking it might be too low of light.
It got a bit more brown since i moved it up.
Current parameters are:
Alk 7.8 (still raising it using balling c and dialing in AFR)
Calc 400
Mag 1400
Nitrate according to ICP 0.1 (dosing now, 2ml a day according to instruction on the bottle, cant remember the brand at the moment)
Phosphate 0.04 (also dosing 2ml a day, same brand as nitrate)
Salinity 1.026
I have two ai hydra 26, pushing full 90w for peak of about 7 hours, with 2 hours ramp up and down, so 11 hours in total. In sync runs a orphek or4 on 50% max power currently.
Is this normal or what could cause it? I hope i provided all the necessary information already!
Here is a FTS with the location of the pavona marked:
