acclimating

[dsmooth]

I just switched from current 150de 10000k to phoenix 14000k. How long if any do I need to acclimate my corals. I am using the screen method now .

I used 2-3 layers to get the light level similar to what it was before the light change. I then took them of every 4 to 5 days watching the corals response. If it's not good put a screen back on for a couple more days, then repeat the process.

How old were the 10,000 bulbs?

Oddly enough I did the same thing last weekend (( but 250 watt )), and I didn't acclimate the corals to the new lights. The bulbs that I replaced were only about 5 months old, and had higher PAR then the Phoenix bulbs, so I didn't see the need to use any screening. My corals are doing great.

The bulbs were aprox 3 months old.

The Current 150 watt 10K's are pretty bright lamps. Most likely still Higher par than the 14K phoenix 150 watt lamps if the currents were only 3 months old (I have used both lamps in the past). You can use the window screen method to play it safe but I doubt it will be needed.
