Corals not doing good

[ravalos2282]

How long have you had them? When they started to decline? What kind of lighting and intensity? Any other corals, how do they looks?

I’ve had them about 4 months par lighting is around 91 were I have them

I would do 25% waterchanges for the next week (once per day) with water that has perfect parameters (freshly made saltwater is).

If you haven't done them for a while not only your parameters are off but also built-up from unused elements which might get toxic if they are too high.

Waterchanges are the best way to get your corals happy again.

I noticed about a week ago

Looks like they were picked at…..anyone in your system could do that.

That’s a lot of receding in a week.
