need some t5 bulb choice help

[jolson10450]

So i need new bulbs and am still in debate what to get.

i currently use front to back:
blue +
aquablue special
kz fiji purple
blue +

i was going to replace them with all ATI
blue +
aquablue special
purple +
blue +

but after seeing the color spectrum charts on reefgeeks website i can't decide and might do:

Front to back:
purple +
aquablue special
purple +
blue +

or

Purple +
aquablue special
blue +
purple +

if you look at the color charts below you can see that the purple + is only a tiny bit less blue than the blue + bulbs but it gives you a good part of the red spectrum so i am thinking of scrapping the fiji purple and a blue + for the extra purple + to get more of the red spectrum as well.




any thoughts on this?

4x 24w t5 retro fixture with icecap reflectors.

bulbs in place 1 and 4 are on a switch and 2 and 3 are on a switch. bulbs 1 and 4 are on an hour longer before and after 2 and 3 to simulate the sunrise/sunset effect with just the blue + bulbs to give you an idea of what i currently do.

any thoughts would help immensely!
