UV light from the Prime HD

Hi,

is it safe to use at 100% the UV light from my Prime HD ? can it do any harm to the coral/fish ?

Nope it's fine. There's ancedotal discussions in it helping with destroying pathogens. I wouldnt read too much in to it but the theory i guess is sound.

The zooxanthella will protect the corals by producing that sunscreen we all love. Vibrant colouration. This is geared up in presence of UV.
