Hello, I have a frag of utter chaos zoas that started off really strong, went from 3p to 11p in a month. then over the last 3 weeks they have started shrinking..they still open but remain super small - see pics below
Any ideas what would cause them to do this? I thought potentially vermetid snails that have grown rampant, there was one in the middle of this frag that I just superglued over to kill but its been a few days and no change.
I have another frag of zoas right next to it that is still open and growing polyps. most other coral seems perfectly healthy - aside from my clove polyps which most are closed except 2-3 are completely wide open..
I run my xr15 about 7 hours a day at 35% - ramping up and down an extra hour or so.
params:
temp - 78
salinity - 1.025
nitrate - 0
pH - 8
phosphates - 0
calcium - 440
alk 6.7
Should I stop doing water changes to get nitrates/phosphates up? I've been feeding what I consider heavy, but doing 15% weekly waterchanges on the tank which is a Nuvo 10, also running carbon - wonder if its just too clean..but I started getting hair algae issues so then again maybe not?
