Marine plant (Codium) bleached/died

[Rivus]

This plant (right side) went from green and healthy to totally white in just over a day. Everything else appears healthy...the Xenia are doing too well! All parameters that I test for are normal. But I don't test for CA yet. What could be the issue?

How long was it in the tank?

 

[Rivus]

10 wks. Showed no obvious signs of stress. Turned completely white in a day, maybe day and a half. I was gone for most of one day.

Did you increase your lights or make any adjustments to the lights? Algae can bleach just like coral from to much light.

Nice looking tank by the way. I like your rock scape.

Thanks, no changes were made to the tank. It's a Max E-170, 45 gallon set up in April this year. I do have the Hydra TwentySix HD LED's set high, but that was since the get-go. Maybe too much for the algae but I would have thought I'd notice stress not total bleaching in a day.

[Rivus]

No, the bright white, now skeleton looking, thing in the back right corner....oh, you see it now.

Ah yeah it probavly went sexual. Meaning it released its internals and accompanied seeds. Usually from low nutrients.
