Could melted ai prime lens harm corals?

[20gallonreefer000]

I've had the light for around a year. I run it at 100%, 12 hours a day so it gets pretty hot. The lens has melted a good portion. The tank is over 2 years old and has been decently stable with no major coral die off. Within the past few months I've noticed acros aren't doing too well(bleaching/losing colour) and coral growth has halted. My parameters are all where I normally keep them and I haven't changed anything major. Does anyone have any negative experiences with a melted lens and coral die off? Thanks.

Replace the lens and you should have your answer

Id rather not replace then lens if I don't have to. Why I made the post.

I would change the lens regardless. I think there are some aftermarket options.
Often with coral its trial and error to figure problems out so starting with something obvious that should be corrected anyway seems logical to me.

Agree with changing the lens. If it is the only thing that is different, yet corals are behaving differently, it's reasonable to suspect lens distortion is somehow having an impact.

Of course it's also reasonable that "haven't changed anything major" isn't major to you, but might be to your coral.

Bleaching/ death is probably due to the lens yes. Either via no lens to assist with light direction, or just the plastic melting and being a toxic substance within the tank (if you have an open top)
