Whats going on with my corals?! Added a new BTA and they are closing up

bjmartie · Jan 8, 2023

So i added a new BTA, making it two BTA in a 90 gallon tank with a 40 gallon sump. I added the second BTA a week ago, 5 days after adding it, i have two Zoas close up and a poly. They have always been fine until recently.

KH:11
Ammonia: 0
Phosphate: .14
Calcium: 440
PH: 8.4
Temp: 78
Salinity: 1.024

i do around 10-15% water changes weekly.

Nitrate reading? Age of tank? Did you have your hands in the tank?

BTA spread its seed.

Bold statement.

Probably, but that's the first thing that popped into my head.

I'll get the nitrate when I get home today. Yes I had my hand in the overflow to fish out my clouded wrasse that got into there. Tank is right at 7 months currently.

I noticed the new filefish I got was picking at one of my zoas last night. I did move him to my qt tank to see if everything opens back up in the next day or so.
