So a couple weeks ago my previously healthy and happy zoas all started closing. I briefly thought it was due to low iodine as they perked up a little with increased water changes, but now are flagging again. Today I noticed a bunch of little white dots on them, see photos. Is this zoa pox?
From reading up I keep seeing Furan-2 as the go-to treatment, but it appears to have been discontinued…
Salinity: 35ppt
pH: 8 to 8.1
Temp: 78
Nitrates: 40
Phosphates: 0.1
Calcium: 420
All: 8-9
Mag: 1450
All my stony corals are going gangbusters - hammers are growing fast, Moseleya growing out nicely, Acans are growing and budding, new Hydophora growing fast after 2 weeks in the tank, new Digitata growing out over the attachment to the rock, all nicely colored up, fish are spawning, everything seems happy except my Zoas, that should be the hardiest things in there.
