Important lighting question

[kyleThatGuy]

Ok so I’ve got a A80 that got a closer look at my fish and when I retrieved it from it’s little swim after letting it sit it flickered but now it’s staying on....well now I’ve noticed it can’t go all the way white anymore so I think some of the lights bulb diode whatever you call them thingies aren’t working so will it still grow corals? i planned on replacing it with a 160 but keeping it on the tank as well or should I just retire it

If not all the leds are working you will not get the full spectrum it was designed to output. Some corals maybe ok some might not

Once the light drops in the saltwater, it’s finished in terms of safety.
The salt will start to quickly corrode the electronics and may short circuit at some point.
Retire for safety.
