Acclimating corals to strong led system?

bmackcw · 08/02/2015, 07:20 PM

I just got this 300w maxspect R420R, replacing a six bulb T5. Should I be running it at, say 50% for a couple days? Not sure if it's that much stronger than the T5 with six 64w bulbs. Thoughts?

i went from 2 250 MH to a evergrow LED last week and my research says to start at 35-40% and go up by 5-10% per week and keep a good eye out for bleaching or anything. or hang them high and slowly drop them week by week but the intensity is easier with a programmable fixture.
50% may bleach them right off the bat. Most people dont run there LEDs at 100% even after full acculmation. I started at 35 % peak for 4 hours dailyand will go up 5% a week until I see the corals are not happy then I will extend the max% time they are on by 1/2 hr a week until I reach a timeframe Im happy with.

Yes gradually increase the intensity.I have a MS 15 K 320 watt on a 220 gal. 30" deep,and it has bleached several leather corals,near the bottom.
