Coral not doing good after dosing acropower

[Fishingandreefing]

I was excited and dosed my tank with acropower 2ml for the past two days. Since day 1, my duncan colony closed up but all other corals seems doing fine. Is this something normal that the coral got irritated by “foreign” solution but will be adjust let say a week later?

Btw, I have a 120g and 30g sump, 2ml is just about half of the recommended dose. I check my parameters and they were the same prior to dosing.

I dose it all the time in a similar size tank. I dose 50ml twice a week with no ill affects. IMO it is a coincidence. and

Coincidence. You're dosing so little in such a large volume.

Hopefully it’s coincidence. I got it from premium aquatic and it was sealed, so I don’t think it’s the product. Will see and update.

this colony was doing really good for almost a year and this is the first time doing this. The only new I am doing is started dosing acropower.

Hopefully, I have nothing but good things about this product but I will see.
