Back wit da 20k

more actinic light= LED's less heat too, i kinda like the led tubes that the icecap fixtures come with, just like a t5 but led's inside

I have two blue LED modules at the moment in the half circle....mainly used for before and after viewing of the MH....they barely do anything when the 2 x 250w MH's are on

I know someone else that has vhos in their half circle.... lol but I think you will really like the 20k I know I do but like I said earlier I need a little spurt of growth.

Are they using a canopy? That's where the problem is at for me. I have two wood panels that I mounted into the canopy and each has a led strip and 250 w MH retro setup. Perhaps if I had MH pendants hanging above the tank and right over the canopy where I have the wood panels at it could work......but not likely that I'm going to hang anything from this SUPER HIGH ceiling.

I will have an opportunity to explore ideas when I tear the tank down in August for my tank move. I have another tank that the corals will go into for as long as I need. So, I have some maintenance that I would like to do to the tank and perhaps kick some ideas around for lighting.

This is awesome! Welcome to the 20K club! I dont have a whole lot of experience with MH but I did have 10K to start with then I got the XM 20K bulbs and it was a little too blue for me at first but I love it now! I wouldnt have it any other way. Everything seems so much happier with the 20K vs the 10k bulbs. I am watching the color transforn from a dull color to a vibrant color in my corals. Amazing what good light can do.

Phoenix 14ks look super righteous.

I have my middle halides at 20k and my outers at 10. It looks funny when all of the lights are on, but in the AM, just the middle lights are on. I get the best of both worlds thadda way I guess.
