Limited Spectrum Choices

[boulderman1]

don't ask how or why but the only bulbs availible for my new 48'' t5 ho 8 bulb fixture on my 90 gal. are:

actinic, 11,000K, 6500K super daylight and 5000K (full spectrum??)

i was thinking of maybe doing 4 6500k, 3 actinic and 1 11,000K

i don't really know what any of these temps look like other than actinic, i want my tank's sand to look like a brilliant pure white and my corals to flourece a little bit, what combo would you guys use?

also, could someone tell me what the purpose of each color is and what it looks like so i have an idea of what your combo suggestions will look like, thanks

The 6500k might look too yellow. At least I didn't like them on my 90 Gal. I would go with 4 11000K and 4 actinic. I have pc bulbs on my tank with 2 10000k and 2 actinics and I like the colors. I'm not a lighting expert. Some of the other members can give you more detailed info.

It's hard to tell someone which ones,some like it bluer and some like it whiter.
