Hello we need help find out out what is wiping out our Zoas, we lost two euphylias Hammers (but torches seem to be doing fine)
It started probably 3-4 weeks ago, and it seems to affect a colony at a time.
We were also dealing with Cyano issue (no red, green) and we just did the ChemiClean last week.
My parameters below, our system used to be more rich on Nitrate and Phosphate, but we been trying to get it more under control and the numbers are a bit better; however it seems corals used to like it more before because we didn’t have this problem, only the green sand bed.
We added a little refugium which to us was hard to manage and lasted only about a month (will like to try this again on the future), we do weekly water changes of 30 gallons on a 155 gallon system including sump.
Filter socks changed at every water change, and UV light is on.
Current Levels:
Nitrate 9.5 via Hanna
Phosphate .08 via Hanna
DKH 8.6 via Hanna
Calcium 370 via Redsea
Magnesium 1240 via Redsea
Salinity 1.024
PH 8.15 via Salifert
Ammonia 0 via Salifert
Thank you for your advice.
