coral light acclimation
the other day i finally got my new light (250w HQI, 2 65w PC, moonlights) i had just PCs before. so i dropped al the corals to the bottom and away from the direct path of the HQI. my question is, how long should i leave the corals on the bottom before i start to move them back up onto the rock work?
few days? week or 2? thanks for the help.

You have much more experience than I do, so I'm not sure if I'm right. But, I had posted something in one of the LPS threads asking a questions about moving things around. It was suggested by someone not to move them more than 1-2 inches per day when acclimating as they adjust fast and it could shock them. Again, I'm not sure how right this is, but that was information I was given about a week ago. Hope it helps and good luck.

you can either accomplish this by using layers of window screen [taking one off each day] or by reducing your light duration to one hour and then increasing it each day, by an hour, until you're at the target duration.

Probably the easiest method, if you have the materials, would be to put egg create and glass on top of the tank to block some of the light. Like Al suggested placing the lights a little higher would help as well. This way you don't have to remember what liked to be where and don't have to stress the corals out more by moving them. You'll notice a lot of the corals will use there energy to slime over to protect themselves from your dirty hands.(they are germaphobes like me and don't like to be touched)
Just be careful not to completely cut off gas exchange at the top of the tank, which will effect your water chemistry, and be careful not to have anything melt or burn. Good luck. |

mspad, I would disagree with that. The intensity of the light is the trouble. If you put a coral under too much light you can see it visibly retract it's polyps and behave differently then it would if it was happy.

mspad- doesnt sound like a bad idea if i were switching to a stronger bulb, but i went from around 100watts of PC, to 380watts of HQI and PC. i think any of my corals near the center would have freaked out.
i was goin to do the window screen way but then decided to reaquascape so i just put the corals on the bottom. i did only have the HQI on for a few hours the first day and am increassing the time its on. i will end up having it on about 8hours out of the day, with atinics commin on an hour before and turuning off an hour later. so for no they are on the bottom (and seem happy) until i move the rock round.
