How Much Light can I put over my xenia and not BURN THEM

marinerules · #1 05/06/2006, 03:37 PM

Right now I have a 240 gallon tank 8x2x2

and my xenia is in the middle and I have
odyssey compact flourescent light (64x4 watts
and 80 watts of Regular t-12 10 k flourescent

so thats
336 watts , and the xenia is half way up in the tank

I have 2 250 watt metal halide bulbs, but I rather now use them as I think they are too blue

I was wondering if I could ge ta 10,000k 400 or 1000 watt metal halide

but that might burn them

I LOVE THIS STUFF, and I want to grow as much as possible

I have 3x400w MH and 2x160w VHO over my 125g (22" deep and the lights are about 7" from the top of the tank), and I have Xenia growing at various places in the tank. There is some about 6" from the top and I have some on the bottom too. It all seems to be doing fine. I do recommend photo acclimating them though.

ok , I think I am going to put both halides over my xenia

thats 500 watts instead of the 336

but I dont know if it will grow better or not due to the bulbs bein 20 k bulbs

Just make sure that you reduce the photo period and slowly increase it so everything is not shocked with tons more light.
