ah, but if were dealing with bulbs for suppimentation, then worth while is in the eye of the installer. the main point of suplementation is color and obtaining the color you like is very subjective. myself personaly I don't like a real blue tank, only ice white.. so the slightest hint of blue, the next guy might mike a real purple tank, and ome even yellowish.. Personaly I went through 12 MH bulbs and about 4 PC bulbs and 4 VHO bulbs beforI found the combo that I liked.

I was just thinking about what every one has said here and I'm thinking of this mix. 1 Fiji purple 2 geis actinic plus and 1 kz coral 2 light. This reason I'm thinking of not going all supplemental light is for in the summer time I don't have to run my mh everyday and deal with temp issues. I don't want to spend the cash on a chiller just yet lol what do you think?

sounds good, I would still try for an hour or two of MH if temps allow.

so set your T5's up so you like the look with out the MH, and with the MH. might take a bit more fiddling to get it looking good.
