Looking for high growth rate t5 combo

Both should give you good growth and color.

 

That is going to make your tank red, just speaking from experience, and that was with 6 bulbs.
If you want a whiter look then get the blue+, actinic white, GE6500, Blue+ combo. That will give you plenty of PAR as will the Blue+, ABS,Blue+, ABS combo.

 

I understand the red the aquasun gives and I agree with ur experience. However Im ok with this because I have blue Led strips along with the 2 blue+ to offset this and I actually like the look. It brings out more colors. Plus from reading online I was told aquasun has the 2nd most amount of par behing the ge6500.

2. Would somone be able to answer the other question? Does Par=growth or does Kelvin=growth?

3.I want my 4th bulb to be a high par bulb. but im afraid an aquasun and a ge6500k will just not look good together. plus out of the 7 LFS not any of them carries GE bulbs.

 

Color temp is kelvin, so in a sense it will sort of give you an idea of the growth potential of the bulb. Lower kelvin, normally means higher PAR. So a 6500K typically will give out more PAR then a 22K bulb.

I have used the GE 6500 with a Actinic White bulb with good results.

 

Btowned is generally correct, T5HO bulbs can be customize for color so much that the blue bulbs have the same or even more PAR than the white bulbs. I would suggest using an ATI Aquablue Special as the 4th bulb. It look white with a hint of blue and would be a good complement to the other bulbs.
