my coral is melting, why?

Yeah, carbon can be a double-edged sword. Dulcia, what's your salt mix? Some brands can be inconsistent, especially if you're not mixing it long enough.

Mixing time's huge. I always let mine mix overnight. Also, check your RODI water. TDS creep can mess with things over time.

I'm using Red Sea Coral Pro, mixing for about an hour. RODI reads 0 TDS. Bulbs are 6 months old. No carbon running right now.

Hmm, sounds like you're covering the basics. Maybe it's just stress from the rock move. Corals can be drama queens sometimes. Give it a few days and see if they bounce back.

For real, they're like moody teenagers. Dulcia, if they don't improve, maybe try dipping them. Could be something invisible bothering them.

Lol, moody teenagers is right. Dulcia, you got any fish that might be nipping at them? Sometimes they get sneaky when you're not looking.

Good point. I had a clownfish that turned into a coral bully out of nowhere.

Fish behavior can change fast. Dulcia, keep an eye on them, especially at feeding time. That's when they're most active.
