Blasto Not Expanding

[T-J]

Today I noticed that my blasto isn’t opening up all the way. Yesterday I installed a new UV on the system, which is the only significant change. I’m battling some Dinos, so I’m wondering if it’s reacting to Dino die off from the UV?
Other LPS corals don’t show any change. Ideas?

Sometimes corals just have an off day and don’t open as much, I wouldn’t worry about it unless it lasts another day or two.
