Closing

[kaspm]

So I'm very new to the reef world and had a quest about the coral I bought yesterday. It seems the polyps are shrinking or closing up all together. Any thoughts as to why?
Temp 78
Ph 8.2-8.4

No ammonia, nitrate, nitrite

You gotta have at least some measurement of nitrate. What test kit?

What are the other parameters?
