Hi Jarred1,

The "irritation" that some talk about is when we blow the food (target feeding) on the polyps and they close...
If one try to drop the food on the poly without much water flow, will see that they actually grab the food particles and close.
When they open the food is gone, as I've posted before...

Irritation is caused by algae and other organisms. When there is irritation the polyps close and don't open until the organisms is not touching them anymore.

If you blow only water one polyps they close, yes, but they open fast. That's just a reaction from the blowing on them.
When a hermit crab touch the polyps, for example, same thing happens... they will open as soon as the hermit goes away.
