About a month ago I had an unnoticed reactor failure which caused my nitrates to go over 100ppm. At the same time a lot of my zoas closed up and melted away.
Since then I've got the nitrates back in check several pretty large 50% water changes, and I've also started running an algae scrubber which has helped to slowly bring nitrates down.
My filtration consists of a arcadia gyractor with bio pearls, bubble magus G5 skimmer (running Ozone), and a algae scrubber.
As my tank stands today my params are as follows:
NH3: 0.003ppm (on Seneye), 0ppm (Red Sea + API).
NO2: 0ppm (Red Sea + API)
NO3: 20ppm (Red Sea), 30ppm (API)
P04: 0.02ppm (Red Sea Pro)
PH: 8.14
Temp: 25.8c
ORP: 188mV (vs RO water tested at 177mV)
Based on these params I decided to purchase some more zoas for my tank. I found a big zoa garden on a rock at my local LFS and put it in my tank.
On day 1 all zoas were closed (to be expected), by day 3 half of the zoas had started melting away. The other half had opened but were shrivelled in comparison to how they looked in the lfs. I decided to put a big bag of carbon in the sump to see if this helped - it didnt'! Now the rock is just covered in the slime of dead zoas
The zoas are not near any corals that could sting them.
My tank has a hammer, galaxia, pink bta, some sps, lots of mushrooms, green star polyps, trumpet coral, elegance....all of these are looking healthy with the exception of the elegance (which has been closed for a few days).
What gives?
