Favia dying

[cruxNC]

I have this plate, it was the first bigger piece that I every bought this passed November when I started my tank. It had one tiny spot on the edge, that was thought to be sand trauma. Over months it has slowly retracted and looks like it is in a death spiral now. It is loosing polyps, fine hair algae is taking over and every day it looks worse. Everything else is happy and my parameters are in range. What am I missing? Can this be saved?

Looks like hair algae.

Consider some utility fish, snails and other inverts

What type of lighting?

Calibrate and double check chemistry.

I have a bunch of snails, the light is on 8 hours, it is a hygger light.

How many watts, how large is the tank?
Different snails and hermits eat different things.

19 watt saltwater aquarium led light fixture contains 48 x royal blue (440-445nm), 24 x cool white (7500K) and 24 x U-V (395~400nm ) LEDs that provides the right light spectrum reef-building corals need for growth. It uses 395nm diodes. The tank was a 10 gallon until a week ago. Now a 20 gallon long.

two turbo, two red banded trochus, two Astrea, one nassarius. one small blue knuckle hermit.

Hope that helps.

IMO it needs a stronger light. I have a 55 watt light over my 15 gallon 12” depth

Bumping up the lighting would be a good intervention. Shoot for at least 65 watts.
Smatfarm, Popbloom, Nicrew, Viperspectra are a few just to look at.

Maybe think about an Urchin.

Posting the values for N/P would be of assistance.

Hate to ask but what are your water parameters? Coral like that often do okay with moderate light and flow but chemistry is often a problem. I ask because of the hair algae. Perhaps your nitrate and phosphate are too high? Also I’ve seen a decline in my coral if Alk or Ca are way out of whack. Hope things improve for you. That’s a nice piece and was probably expensive.

Everything is pretty good.

Not great. I need the address KH the most I think
