Lighting

[Deontae]

Hey guys I’ve been running a current led light on my 20 long for the last year, but now that’ I’ve upgraded to a 40b I got new lights. I got the 300w viparspectra leds. I know the current wasn’t the strongest thing so I’m just wondering what I should set my new lights at so that I don’t bleach my corals. LED is hung 7 inches above the water.
Thanks

I have the 165w. So your par may be higher. I have it hung 15inches off the water running it 35/1 blue/white I get 200 par 6inches down on my 20glong. Hopefully a 300 watt user responses to your thread here.
