So I've burned the last 2 batches of SPS to LEDs,
Currently using 3W Crees LEDs and had blues at 100% and whites at 75%
Using 2 x 120W fixtures, each with 24 blues and 24 mixed LEDs = 96 total LEDs with 240W total at 100%. over my 3 foot, 65 gallon tank.
Compared to my old 200W T5 fixture, I assumed I was just bumping it up a notch, but I see now I bumped the lighting up WAY higher than my SPS could handle and I calculated my numbers thinking all watts were equal (blues at 100%=120W and whites at 75%=90W equals 210W in total)

When I first replaced the T5 fixture with LEDs, I was too conservative and slow with the light increase per week that half my corals died out. Now I'm increasing them too fast.

What is your acclimation schedule (time frame and percentage light increase) when you place new SPS or LPS for that matter?
for example, should I start with blues and whites at 25% for a week, then 50% for week 2, etc?

I never go above 80% blue and 55% white with my Fathom Hydra series LED. I tested 100% blue and 75% white and started getting algae growth on the tips of birds nest but my digi looked fine.
I lowered back down to 80% and 55% white, Whites are their peak for 3.5 hours blues at max for about 5 hours. before and after ramp up and down from 1%. MY LPS take whatever i throw at them.

They are 10 inches above the water level. I'm looking for acclimation procedures which would apply to all 3W LED situations.
So I can turn up the dial at 5% increases, but what do you start at?

If I recall correctly, when I started in the beginning, I started blues 25% and whites at 15% then dialed them up 10% every 2 week, but after 6 weeks or by 55%-65%, they were already starting to die out because it was too dim for too long.

Then, I'm started around 65% and bringing them up to 100% over 3 or 4 weeks, which seems to be too fast or too bright, or maybe both.

SO, now if my arbitrary max target is blue 75% and white at 30%, what should I start at and how many weeks should it take me to hit my goal? 5% increases per week for 4 weeks or 5% biweekly for 4 weeks?
