I'm pretty sure it is because of my recent nutrient problems that I'm having problems with hydroids and in the long term they probably will start to disappear on their own...unfortunately that doesn't help my ailing corals in the short term

I tried kalk paste to no effect.

Turned off the pumps slowly encased them in paste for hours and a few hour after the pumps back on, they were out again.
