Best growth combo (T5)

[350gt]

Well my 30" fixture only has 4 T5s, whats your opinion on bulbs for best growth?

The bulbs will more than likely be ATi but debating on a GE6500 in the mix for growth...


Anyone have some knowledge and first hand experience they can pass on?

Getting mixed reviews on the GE bulb causing algae problems.......

Yea, I have used the GE before in my 4 bulb setup and it is almost too yellow. Right now I am running 2 blueplus, 1 aquablue, and 1 of ATI's new coral plus. It is not super blue, probably close to 15K or so. Before that I just used 2 blueplus and 2 aquablue and my SPS growth has been pretty good, although my coloration kinda stinks... not sure if this is related to the lights or not...

i run a six bulb with 4x blue plus, 1x ge 65k, 1x fiji purple, no algae problems from bulb and ive used a kz 65k bulb before which is also a good bulb

IMO i would do 1 fiji purple, aqua blue(or coral plus), 2x blue plus or swap one blue plus for a coral plus

It is not quit as purple as the Fiji, but does seem to put off a slightly purple tint. So it's kinda like there aquablue with a slight purple tint to it... if that makes any sense.

I ordered 2 blue plus, 1 ge65k (to test), 1 aquablue, and 1 true actinic which I just went back to see if I can swap for a coral plus.

ordered a extra to mess with the color combo a bit....

I will probably sill try and add some leds some where in the mix.....

[Squiers007]

Sounds like a good plan. I am considering adding in a strip of LED's as well...

When I ran T5's I used 2 454-460nm blue actinics, a blue plus(14000 or 15000k) and a 6500K for color, but you said for growth combo so I probably would have went with a 10000k. From what I understand 420 nm and 6500k don't produce par intensity like the other bulbs
