halide upgrade-need help!

[bv_reefer]

i'm getting an XM-400 watt 14k bulb, 12'' off the surface minimum, start a photoperiod of 3-4 hours, gradually work it up to 6-8 hours-

heres all my corals and inverts, think any of them will take the lighting change really negatively?

-xenia colony, ricordea, 2xfinger leather colonys, monti cap,cup coral(lps one), kenya tree, long tentacle plate coral, condy anemone, green star polyps-

400w is okay, I did it on a 46g and got great results. Just remember to watch your temperature and be ready to acclimate all your new purchases in the future.

Looks like you have under control. Just make sure you keep a close eye on your corals for signs of stress. You'll be riding the ragged edge with that setup; the outcome will either be glorious or disastrous

Oh, I see you're getting the XM 14K bulb (isn't that 15K?), a notoriously low par bulb. Should be your safest choice for that setup.

Agree it will be great for acclimation but you might want to switch them with a higher par bulb later. What Ballast are you going to use?

the type of the ballast i will find out today, but what do you meen higher par?
does that meen higher kelvin, or better quality bulb?

[Reefer Rob]

"Photosynthetic Available Radiation" or something like that.
