Acan Melted

[Old Glory]

Hi I have a fairly new tank 3 months old. One of my Acans melted last night. Was retracted then gray this morning. I used a baster to gently blow away the gray and it was dead tissue.

Parameters:
Salinity 1.025
Alk 11.2
Ammonia 0
Phosphate .04
Cal 290
Nitrate 0

I have about 120 gallons of water. Run a skimmer, carbon, and GFO. Dose 6 ml NoPox daily. 10 ml Vibrant every two weeks. Just changed water Monday 20 gallons. All other corals seem fine except for a Red Dragon frag.

I am going to lower Alk to 10 and try to raise calcium.

Thanks for an suggestions

CA definitely low and ALK a bit on the high side. Lighting and flow are also quite crucial for acans; and most coral... How often do you test? Are you experiencing parameter swings?

 

[Old Glory]

I generally test weekly. Everything has been pretty steady except for the drop in calcium. The Alk was a slow climb but I will bring it back down. Also Phosphate had been holding steady at 0 but I attribute the increase to starting to use Reef Energy A+B 3-4 times per week.

 

[CodyRVA]

Honestly, any of those factors individually or cumulatively could be responsible.

I would have to say the higher Alk was the demise of the acan.

Alk is high, but it could be bjd (yes, it can be grey) but I can’t make assumptions without pics...
Also imo, vibrant is no bueno.
Ran into all sorts of problems with my lps and zoas when I “tried” it...
Never again!

IMO Definitely has to do with the Alk and/or Calcium. I had quite a few Acans doing amazingly and then the all dropped to like 6 and calcium to 360ish and they all wasted away within two or three days . Thats my experience at least

I used Vibrant to cleanup a golf course, all acans were fine, maybe it was your dosage amount and how often you dosed

No, I did everything to the T...
I didn’t like it!

Ok, just stating a fact, it worked wonderfully for me. Took out a green golf course, also rocks were loaded. Corals were fine, 9 different Acan colonies
