20k?

danielmar, you use 400w bulbs. that is a huge differnce in lumens/par compared to a dinky 150w bulb. compare the par value on a 150w 20k and a 400w 20k.

I got the Phoenix 14k now,& everything in my tank is burning up.I moved the light up from 8" to 12",cut the light cycle in half.12hrs to 5 hrs,& 2 layers of screen.Now i have moved everything to the bottom ,& can only hope everything lives.

so accordin to expedition.. the phoenix 14k is defenitly too hot.. so im guessin a 20k xde bulb would be just about right

iku,my clam is the only thing that is ok.

well, i have alot more soft corals in my tank than just one clam.. so im tryin to make everything happy and healthy instead of just having one happy, and rest of them burnin

I should have stayed with the 20k,everything was looking,& growing great.

IKU, do you have the clams already? How big are they? If they are under 2 1/2 to 3 inches they will need to be fed DT's anyway and the color temp of your bulb is not really as important. It will get you by for 6-10 months and you can get a better suited bulb.

give the tank some time to acclimate to the new light. this will take a long time. it may take a good month or two. moving the light up will help. you will notice that the coralline algae will be first to go. it will come back. usually a different color though. i am learning that a reef tank is more of a lesson in patience. nothing changes quickly. corals take a long time to adjust to changes in light, salt, & chemicals.

snprhed, the clam is about 3 1/4 " so i dont think it needs to be fed; just feeding him light is what im doing right now.

After things get acclimated they will look great too..and probably grow faster with the 14K () : )

You hang in the SPS forum Expedition, You know know this stuff () : )
