So Friggen Confused..... T5 bulb comparison help

[freddy]

just switched my t5's to geiseman,well 3 out of 4,I have 2 aqua blue plus and a atinic plus,noticed a huge difference,the aqua blue has a nice crisp white look,then I put in the atinic plus and it added a blue tinge not to much but just right,my zoos seem to like the new light alot,my fourth bulb is either going to be another aqua blue plus or another atinic plus.
