changing kelvin rating on a new RBTA

[DMK]

i have a new RBTA. all lights were just replaced but now i want to switch from 14K to 20K. would this stress new RBTA? it's only in about 4 days and am thinking about switching lights by end of month.

Why do you want to switch from 14 to 20K??? 14K lights are better for the RBTA. In fact, 6500 to 7000 K is the most natural spectrum that anemones prefer.

No, it shouldn't stress the RBTA too greatly. With dual 250s, they should still get plenty of PAR. However, you will probably want to either raise the lights and/or shorten the photoperiod initially to allow for any intensity issues between the old bulbs and the new (as you should whenever you replace bulbs).

i'm not positive on it yet, but reason is my mag ballast burns bulbs whiter than they really should look. i think a 20K would be best for my SPS coloration. i couldn't decide when i last ordered and now i'm kind of wishing i went 20K. also i think the RBTA would definately look better w/ 20K, but i don't want to stress it, being it's still new and all...

Yes 20 K would look awsome with either sps and especially a RBTA. Good luck!

We have a 20k over our rbta, but my tank looks too blue to me. We have two lights (although we still need to get one more bulb) and I think I'm going to run a 14k on the other side to balance it a little bit for my liking.

what ballast?

i'm sure it would look good for corals and rbta. i'm just concerned w/ stressing new rbta. i think i've decided overnight to just leave 14ks on for a few more weeks, until rbta is good and settled. it seems pretty settled already though. only moved about 3" in almost a week. i just wish it would turn alittle foward around rock, kind of facing back now, cannot see mouth unless i turn off all circulation and look from top down...
