Light acclimation ideas

[Bosco83]

My Reeffiltration LED's will be here next week and I need some ideas on how to acclimate my corals since these fixtures aren't dimmable.

Thanks,
Brian

keep the LED's 2-3 feet off the surface and lower them over the next week or two. Or you could put some egg crate panels to diffuse the light. Add a couple layers of light diffusion panels on top of each other(staggered a bit)...then when your comfortable remove one... give it a few days to a week...then the second.

Instead of multiple layers of eggcrate, you could use one layer of eggcrate and 3-4 layers of window screen material. Remove one layer every 4-5 days.

Good ideas I'll have to make a trip to HD. I forgot to mention they will be mounted inside my canopy that's why I can't slowly lower them down. I think I will use the egg crate with the window screen Idea sounds about the easiest thing to do. How many layers of screen material do you think I should use?

Thanks,

I guess it would depend on how much par the currents lights produce and how old they are vs. how much the new system is. If you are going from real low par to high par, then I would go with atleast 4 layers for atleast 5 days per layer.
When I switched my zoathid tank from 4 x 55 watt pc to a 250 watt mh, I used 4 layers for 5 days each.
I didn't see any light shock problems.

Perfect thanks! I'll be heading to home depot today to find everything. Well right now I'm using 6 48" T5's (bulbs are about 6 months old) staggered in my canopy they were from my 90 gallon when I upgraded to the 210. I just had to save some money to buy my lights.
