Multiple zoa colonies closed up for more then 3 days now

[andre zaharchenya]

As you can see on photos many colonies have been closed up. They were doing good for at least a month.

23 g frag tank and 20 g sump. 4 bulb t5 running for 5 hours.

I increased flow speed on gyre wave Maker recently and zoas on the rock that’s next to the wavemaker have been closed up for a while now.

Are your nitrates always that high? A sudden increase in parameters will sometimes cause corals to freak out and act upset for a while.
