Anything else change in the tank or anything that could be irritating them? Have any photos?

Gah, I need a PAR meter to get some actual numbers here as what the box say's and what others are measuring seem to be different.

I figured since radions are almost double the power of ai I'd lower it in the beginning. But I have Zoas in the tank just totally under the sols and they're wide open and expanding.

I guess in a few days I'll have my answer now that I've swapped the lights

I'll take photos tonight
