LED Underwater Lights Antifouling

[tjd24]

Hi Guys,
I have the LED Underwater Lights Option on my 2320 SL. Last year I had a really bad growth problem on the lenses. Does anyone know a safe, reliable antifouling product I can use to prevent this problem?
Thanks

Not an anti-fouling product that I'm aware of, but some bleach on a sponge should clean them right up.
