My JF stargazer zoas have closed up and look like nubs. They don’t look just closed, they almost looks like they’re losing their skirts or something.
they looked similar to the purple monster zoas behind them a week or two ago. Parameters are in within normal ranges except for nitrates/phosphates. Nitrates we’re at 40 last week and phosphates at 0.2.
just tested them again, nitrates 35 and phosphates 0.18. This is after adding chaeto recently and ramping up the photoperiod.
Any advice?
First picture shows how they look now, second is about 2 weeks ago and how they looked.
